On a recent day the difference between the lowest temperature at the highest temperature of the day was 9*C. By how many degrees fahrenheit did the temperature change
Answers
Answer:
48.2 Fahrenheit
Explanation:
Temperature change = 9*C
By how many degrees Fahrenheit did the temperature change?
The relationship between Fahrenheit and degree Celsius is given as;
F = (9 / 5) C + 32
Inserting the value of C;
F = (9 / 5) * 9 + 32
F = 48.2 Fahrenheit

An advantage of using renewable energies is? 1.They are harmful to the environment 2.We have a limited supply of them 3.They allow us to take energy from natural processes
Answers
Answer:
3. They allow us to take energy from natural processes
Explanation:
There are two major sources of energy namely: renewable and non-renewable. Renewable sources of energy are those natural sources that gets replenished faster than they are utilized, which is contrary to non-renewable sources. Examples of renewable sources of energy are wind energy, solar energy, hydro (water) energy.
According to the question, one advantage or merit that renewable sources have over their counterparts is that they allow us to take energy from natural processes e.g. wind, sunlight etc.
why hydrogen and oxygen atoms are more stable when they form bonds in a water molecule?
Answers
The outer shell of electrons is full, so there is no need to gain or lose electrons.
The hydrogen and oxygen atoms are more stable in water molecules as they get a complete valence shell when they bonded with other atoms.
What is the reaction to the formation of water?In a chemical reaction, two or more reactants react with each other under the chemical condition to form two or more products. The Chemical reaction is defined as a reaction two or more reactant components react with each other to form two or more products.
The water is formed by reacting hydrogen and oxygen. The chemical reaction of water formation is shown below.
[tex]H_2(g)+O_2(g)\longrightarrow H_2O(l)[/tex]
The balanced chemical equation can be defined as a reaction where the number of moles of reactants is equal to the number of moles of products.
[tex]H_2(g)+ \frac{1}{2}O_2(g)\longrightarrow H_2O(l)[/tex]
The hydrogen atoms have one electron and the oxygen has two electrons less than the complete valence shell. But in the water molecule, every atom has a complete valence shell so atoms become more stable.

If 0.150 moles of calcium oxide reacts with carbon dioxide gas, how many grams of calcium carbonate can be produced?
Answers
Answer:
15 g of CaCo₃
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
CaO + CO₂ —> CaCo₃
From the balanced equation above,
1 mole of CaO reacted to produce 1 mole of CaCo₃.
Next, we shall determine the number of mole of CaCo₃ produced by the reaction of 0.15 mole of CaO. This can be obtained as follow:
From the balanced equation above,
1 mole of CaO reacted to produce 1 mole of CaCo₃.
Therefore, 0.15 mole of CaO will also react to produce 0.15 mole of CaCo₃.
Finally, we shall determine the mass of 0.15 mole of CaCo₃. This can be obtained as follow:
Mole of CaCo₃ = 0.15 mole
Molar mass of CaCo₃ = 40 + 12 + (16×3)
= 40 + 12 + 48
= 100 g/mol
Mass of CaCo₃ =?
Mole = mass / Molar mass
0.15 = Mass of CaCo₃ / 100
Cross multiply
Mass of CaCo₃ = 0.15 × 100
Mass of CaCo₃ = 15 g
Thus, 15 g of CaCo₃ were obtained from the reaction.

What volume of a 3.00M KL stock solution would you use to make 0.300 L of a 1.25M Kl solution?
Answers
Answer:
0.125L or 125 mL
Explanation:
See the image for steps!0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.
What is solution?A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
What is stock solution?A stock solution is a concentrated solution that will be diluted to a solution of lower concentration.
stock solution = diluted solution
What do you mean by dilution?Dilution is the process of decreasing the concentration of a stock solution by adding more solvent to the solution. The solvent added is the water. The more the solvent you add, the more dilute the solution is.The equation for dilution is M1V1=M2V2Where, M1 = concentration in molarity (moles/Litres) of the concentrated solution
V2 = volume of the concentrated solution,
M2 = concentration in molarity of the dilute solution
V2 = volume of the dilute solution.
The volume of 3.00M KI solution can be calculated using the dilution equation:
Given:
M1 = 3.00M, M2 = 1.25M, V1 = x, V2 = 0.300L
M1V1 = M2V2
3.00M(x) = 1.25M(0.300L)
x = 0.125L
Hence, 0.125L of 3.00M KI stock solution is required to make 0.300 L of a 1.25M KI solution.

I believe it's better for it to be more abundant because it's better to have more then less. Take water as an example. Water is an important factor to our survival and if we didn't have enough of that we would be in trouble. Or if we needed food but there wasn't enough more people would be dying from starvation. It's better to have a little more than a little less.

A compound is analyzed and found to be 50% sulfur and 50% oxygen. If the total amount of the sulfur oxide is 12.5 g, how many grams of sulfur are there? Show work.
Answers
Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
Moles O = Moles S:
12.5g O * (1mol / 16g) = 0.781 moles
Mass S:
0.781 moles * (32g / mol) =
