Explanation:

Answer:

The chemical or substances used to start a reaction are called reactants.

Answer & Explanation:

For the water to H2 and O2 problem:

1) Reactant is H20, it is to the left of the arrow.

2) Products are H2 (gas) and O2 (gas) because it is to the right and what is created.

For the CO2 + water -> Glucose + Oxygen problem:

1) Reactant is CO2 and H2O, it is to the left of the arrow and what is being changed.

2) Products are C6H12O6 (glucose) and O2 (gas) because it is to the right and what is created.

Answer:

They all have the same density

Explanation:

Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.

It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is [tex]19 \frac{g}{cm^3}[/tex].

Answer:

Phenotype

Explanation:

The observable physical characteristics of an organism, as determined by both genetic makeup and environmental influences.

The question is asking about the observable physical characteristics of organisms.

We can eliminate options B and C because they don't make much sense. An organelle is a structure in a cell which conducts cellular functions, and the morphology of an organism is basically the anatomy and physiology of the organism, which isn't quite what we're looking for.

Keeping this in mind, here is some information on prefixes:

geno - relating to genes

pheno - relating to what's observable

The second one sounds a lot like what we're looking for, and just in case, the definition of phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Therefore your answer is: A. phenotypes

d position

position is the reference for the points of the object

Answer:

Explanation:

How many cm of a solution of 0.100 mol dm NaOH are required to completely  neutralize  25.0 cm of 0.250 mol dm H3PO4?.

a) Write a balanced equation for the reaction NaOH to neutralize (4 marks

?. ) 25.0 cm of 0.250 mol dm H3PO4

H3PO4 + 3NaOH----------> Na3PO4 +3 H2O

b) How many moles of H3PO4 need to be neutralized? (1 marks)

25.0 cm3 of 0.250 mol dm3 H3PO4: 1 liter has 0.25 moles. 100 ml has 0.025 moles 25 ml has o.025/4 molea or 0.00625 moles)

c How many moles of NaOH are needed to neutralize the H3PO4? (1 marks)

for every moles of H3PO4, WE NEED 3 MOLES OF NaOH.  FOR 0.00625 MOLES WE NEED 3X 0.00625 =0.01875 MOLES OF NaOH

d) How many cm3 of 0.100 mol /l NaOH contain the moles in question 5(©) above? (1 marks)

1 L CONTAINS 0.100 Moles

100 ml contains 0.010Moles

we need 187.5 ml since (187.5 X 0.100)/1000=0.01875

Answer:

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 500 g

volume = 67 mL

We have

[tex]density = \frac{500}{67} \\ = 7.462686[/tex]
