Difference Between baking soda and baking powder

Answers

Answer:

Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.

Explanation:

Explanation:

baking soda contains one ingredient, sodium bicarbonate. however, baking powder contains sodium bicarbonate , monocalcium phosphate and either sodium acid prophetess or sodium aluminum sulfate

item 3 steel is an alloy containing fe atoms and c atoms. which of the following diagrams best represents the particle-level structure of steel?

Answers

An alloy is obtained when an element is combined with another physically and not chemically. The image that accurately represents steel is the image in which carbon atoms are sandwiched between iron atoms.

Steel is an alloy of iron and carbon. In an alloy, the atoms one element is sandwiched in between atoms of another element in its crystal. Usually, allows are formed to improve certain desired properties of substances. The percentage of carbon included in steel depends on its intended use.

The image that can be used to represent the formation of steel is the image shown in B. In that image, small atoms of carbon are seen sandwiched between larger iron atoms. That is the accurate description of steel.

What two things do astronomers need to know about a star in order to calculate its luminosity or absolute magnitude? A.color and size B.color and distance C.distance and brightness D.size and distance

Answers

(đ) is answer of question.

Explanation:

However, the brightness of a star depends on its composition and how far it is from the planet. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

MARK ME AS A BRAINLIST PLZ

Astronomers measures the luminosity of stars by determining the magnitude of brightness and distance from earth.Thus option C is correct.

What is luminosity?

Luminosity of a star is the total amount of energy radiated by them to a distance. The luminosity vary from star to star based on the distance to them.

Luminosity is basically measured in terms of brightness as observed from the earth. Stars will make a group in certain shapes and certain number called constellation. The overall brightness can be then higher for each constellation.

Astronomers define the brightness of stars by the apparent distance from the earth whereas the absolute magnitude is defined is terms of standard distance of 32.6 light years. Hence, the option C based on distance and brightness is correct.

what is the trend for atomic radii across the periods and down the group?

Answers

Answer:

So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.

Explanation:

Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

GIVING BRAINIEST

Answers

Answer: The clumps, known as glacier mice, have been found to contain miniature ecosystems

Explanation: Because glaciers are in constant, if slow, motion and are frequently blasted by strong winds.

The clumps, known as glacier mice, have been found to contain miniature ecosystems. And even in freezing temperatures, scientists found, the inhabitants manage to thrive. In high winds glacier mice, which form when clumps of dust and organic debris develop a layer of moss over time, hop across vast sheets of ice.

What organisms live in glacier mice?

These included springtails (small insect-like animals), water bears (also known as tardigrades, the only animals known to have survived in space), and roundworms. Globally, glacier mice are rare.

which alkyl halide reacts fastest with trimethylamine in sn2 reaction?

Answers

Structure V reacts fastest with trimethylamine in SN2 reaction. Owing to less steric crowding in the transition state and ease of cleavage of the R - I bond

The question is incomplete, the complete question is shown in the image attache to this answer.

SN2 reaction is a type of nucleophilic reaction in which the nucleophile attacks the substrate from the reverse side. This is a synchronous reaction because the leaving group departs as the entering group attacks simultaneously in a hypervalent transition state.

SN2 reaction is favored by structure V owing to less steric crowding in the transition state and the easy of cleavage of the R - I bond. Hence, structure V reacts fastest with trimethylamine in SN2 reaction.

It takes 40 mL of 0.10 M of hydrochloric acid (HCl) to neutralize 50 mL of sodium hydroxide (NaOH) for the following chemical reaction

HCl + NaOH → NaCl + H2O

The concentration of sodium hydroxide is _____.
0.125 M
0.08 M
0.10 M
0.04 M

Answers

Answer:

0.08 M

Explanation:

here...

1. water and a salt

2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.

3. titrant

4. 0.08 M

5. indicator

{quizlet: captncrun}

The concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M

From the question,

We are to determine the concentration of sodium hydroxide

The given reaction is

HCl + NaOH → NaCl + H₂O

This means

1 mole of HCl is required to completely neutralize 1 mole of NaOH

To determine the concentration of sodium hydroxide,

We will use the formula

[tex]\frac{C_{A}V_{A} }{C_{B}V_{B}} = \frac{n_{A}}{n_{B}}[/tex]

Where

[tex]C_{A}[/tex] is the concentration of acid

[tex]C_{B}[/tex] is the concentration of base

[tex]V_{A}[/tex] is the volume of acid

[tex]V_{B}[/tex] is the volume of base

[tex]n_{A}[/tex] is the mole ratio of acid

[tex]n_{B}[/tex] is the mole ratio of base

From the give information

[tex]C_{A} = 0.10 \ M[/tex]

[tex]V_{A} = 40 \ mL[/tex]

[tex]V_{B} = 50 \ mL[/tex]

From the balanced chemical equation

[tex]n_{A} = 1[/tex]

[tex]n_{B} = 1[/tex]

Putting the above parameters into the formula, we get

[tex]\frac{0.10 \times 40}{C_{B} \times 50} = \frac{1}{1}[/tex]

Then

[tex]C_{B} \times 50 = 0.10 \times 40[/tex]

∴ [tex]C_{B}=\frac{0.1 \times 40}{50}[/tex]

[tex]C_{B}=\frac{4}{50}[/tex]

[tex]C_{B}=0.08[/tex]

Hence, the concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
