A car travels 76 km/hr for 11 hours. How far did the car travel in this time period (in kilometers)?

Answers

Answer:

836 km

Explanation:

76*11=836

Answer:

836km

Explanation:

76km/hr = 76×1000÷3600= 190/9 m/s

11hours =39600 s

Distance=speed×time

Distance=190/9 × 39600= 836,000m

So distance is 836,000m or 836 km.

Answers

Cyanobacteria I think I am not sure

First organisms to convert solar energy to chemical energy were the organisms which are called as cyanobacteria.

What is chemical energy?

Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.

Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.

It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.During digestion chemical energy is converted to mechanical and thermal energy.

What is the empirical formula of a molecule containing 65.5% carbon, 5.5% hydrogen, and 29.0% oxygen

Answers

Carbon(C):
number of moles= mass/molar mass(Mr)
=65.5/12
=5.5 moles

Hydrogen(H):
number of moles=mass/molar mass (Mr)
=5.5/1
=5.5 moles

Oxygen (O):
number of moles = mass/molar mass (Mr)
=29.0/16
=1.8 moles

EF= lowest number of moles over each of the elements

So,
C= 5.5/1.8 = 3
H= 5.5/1.8 = 3
O= 1.8/1.8 = 1

Are crystals of different soluble solids similar?​

Answers

Crystals of different soluble solids  are not similar because they are  amorphous and   therefore  do not have definite crystals.

What are crystal solids?

A crystalline solid is a homogeneous solid in which the constituent particles, atoms, ions or molecules are arranged in a definite repeating pattern.

Most of the solid substances are crystalline in nature. The arrangement of particles in a crystalline solid is such that the total intermolecular force of attraction is at maximum.

Factors in which solubility depends are temperature, pH, and ionic strength.

Crystals of different soluble solids are not similar as they do not have definite crystals.

Only plants cells have a vacuole, cell wall and chloroplast, while animal cells have cilia, centrioles and lysosomes which plant cells don't usually have. Because of their cell walls plant cells are in rigid rectangular shapes while animal cells have looser round shapes. The main difference in their functions is that animals don't produce their own food while plan cells do.

Find the pOH for the following:

A 1.34 x 10^-4 M solution of hydrochloric acid.

A) 10.13

B) 3.87

C) 4

D) 10

Answers

Answer:

A) 10.13 is the answer

Explanation:

Since HCl is a strong acid, its pH can be found by simply plugging it into the equation:

pH = -log[H+]

*H+ is just the concentration you were given*

Now that you have the pH, you just subtract it from 14 to find the pOH

I have attatched my work below. Hope this helps! :^)

To find the pOH of a solution, you can use the formula: pOH = -log10[OH-]

What is pOH?

pOH is a measure of the concentration of hydroxide ions (OH-) in a solution. It is the negative logarithm (base 10) of the hydroxide ion concentration.

In this case, since we have hydrochloric acid (HCl), we need to consider the concentration of hydroxide ions (OH-) produced when HCl dissociates in water.

HCl is a strong acid and completely dissociates, meaning it produces an equal concentration of hydrogen ions (H+) and chloride ions (Cl-) in water. Since there are no hydroxide ions produced, the concentration of hydroxide ions is 0.

Therefore, the pOH of a hydrochloric acid solution is 0, and none of the options provided (A, B, C, D) is the correct answer.
