C) You would expect to have 270 mL of lemonade.
The total volume is the sum of 20 mL of flavor crystals and 250 mL of water.
When you dissolve the flavor crystals into the water, the volume of the water does not change. The flavor crystals mix with the water and occupy the same space. Therefore, the total volume of the lemonade will be the sum of the volume of the flavor crystals (20 mL) and the volume of the water (250 mL), resulting in 270 mL of lemonade.
It's important to note that when substances dissolve in a solvent, they typically do not change the overall volume of the solution. The dissolved particles become dispersed throughout the solvent, occupying the same volume as the solvent itself.

how many molecules are there in 1.5 mol of methane
Answer: A mole of something means that there are 6.02 X 10^23 of that something. So, a mole of methane molecules is 6.02 X 10^23 methane molecules. So, 1.5 moles of methane will contain 1.5*(6.02 X 10^23) = 9.0 X 10^23 methane molecules

The desert climate or arid climate, is a climate which there is an excess of evaporation over precipitation. During the days, the temperatures are very high and dry. During nightfall, temperatures drop dramatically and it gets very cold. In three to four sentences, describe one plant and one animal that you would expect to find in the arid biome. Support your answer with the abiotic factors in the biome. *
These desert dwelling, nocturnal creatures are very tough and low maintenance. Scorpions' exoskeletons and venomous stingers give them great protection, and their low food and water needs and ability to slow down their metabolism allow them to survive in the harshest environments.

Predict the approximate molecular geometry of a formaldehyde molecule:
Answer:
trigonal planar geometry
Explanation:
The molecule, formaldehyde , has three regions of electron density around the molecule. The carbon atom is the central atom in the molecule of formaldehyde.
Recall that each bond around the central carbon atom in formaldehyde- both single and double are counted as a single region of electron density. Molecules having three regions of electron density around the central atom have a trigonal planar geometry.
What effect does this added energy have on the temperature, pressure, and number of collisions?
Answer: Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Does combustion need oxygen?
A. Yes
B. No
Answer: a. Yes
Explanation:
Answer:
A. yes
Explanation:
In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.

For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be produced
Answer:
29.9 g of CO₂ will be produced by the reaction.
Explanation:
This is the reaction:
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
First of all, we state the moles of each reactant:
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
The solid salt is the limiting reactant. Ratio is 2:1
2 moles of acid can react to 1 mol of salt
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
As we only have 0.680 moles of salt, we do not have enough.
Let's work at the product side. Ratio is 1:1
1 mo of salt can produce 1 mol of gas
0.680 moles will produce 0.680 moles of gas
We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂
The number of grams of Co2 should be produced is 29.9 g.
Calculation of the number of grams:Since
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
So,
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
Now the ratio should be 2:1 for the solid salt
And, there is 2 moles of acid can react to 1 mol of salt
So,
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
Now the product side the ratio is 1:1
So, that means
1 mo of salt can produce 1 mol of gas
So, the no of grams should be
= 0.680 mol . 44g / 1mol
= 29.9 g of CO₂
