Answer:

The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun's light, making it appear bright in our sky. Have your child hold the fruit at arm's length, pointing at the light.

hope this helps :)

a 1.513 g sample of khp (c8h5o4k) is dissolved in 50.0 ml of di water. when the khp solution was titrated with naoh, 14.8 ml was

JulijaS [17]

molar mass of KHP ( C8H5O4K)= 8*12+5+4*16+39=204

( atomic weights : C=12, H=1, K=39 and O= 16)

moles of KHP= mass/molar mass = 1.513/204 =0.0074

The reaction between KHP and NaOH is

KHC8H4O4(aq) + NaOH(aq) => KNaC8H4O4(aq) + H2O(l)

1 mole of KHP requires 1 mole of NaOH;

moles of KHP=0.0074

moles of NaOH= 0.0074

concentration of NaOH= moles/ Volume in L, 1000ml= 1L, 14.8ml= 14.8/1000L=0.0148L

concentration of NaOH=0.0074/0.0148=0.5M

The molarity of NaOH is 0.5M

Molar Mass:

In chemistry, the molar mass of a compound is defined as the mass of a sample of that compound divided by the amount of substance. This is the number of moles of that sample measured in moles.

Molarity:

Molarity is used to describe the concentration of a solution. Molarity, also called molarity, is the number of moles of solute (dissolved substance) per liter of solution.

How many moles of gas were added to a balloon that started with 2.3 moles of gas and a volume of 1.4 l given that the final volu

Ierofanga [76]

<span>Ideal Gas Law is as follows: PV = nRT Now lets rearrange so we can get rid of some variables. V/n = RT/P Assuming temperature and pressure are the same (atmospheric pressure), we can get: PV/n = constant (k) Now since we are dealing with an initial state (2.3 moles, 1.4 liters) lets set that as V1 and n1 and the final state as V2 and n2 .V1/n1 = constant (k) V2/n2 = constant (k) Because the constant is the same (remember me making the assumptions above??) V1/n1 = V2/n2 now rearrangement: n1/V1/V2 = 1/n2 -1 = n2 Answer: 11.8 moles are in the final vessel. So to answer the question how much was ADDED, we need to subtract the initial mole number. 11.8 - 2.3 mols = 9.5 mols added</span>

Which choice could be an example of natural processes causing water pollution?

ExtremeBDS [4]

bacterial growth

Explanation:

Excessive bacterial growth is one of the example of a natural process that causes water pollution.

Pollution is the undesired concentration or harmful introduction of a particular body into the environment and causes harm overall.

Pollution can result from both natural and anthropogenic sources.
Anthropogenic causes of pollution are the most common due to activities of human beings.
Natural causes of pollution results from the activities of nature in itself.
From the given options, the bacterial growth is an natural process of pollution.
