Answer:- B. 4.65 g.
Solution:- The given balanced equation is:
It asks to calculate the mass of silver sulfide formed by when 0.0150 liters of 2.50 M of silver nitrate are used.
Moles of silver nitrate are calculated on multiplying it's liters by its molarity and then on multiplying by mol ratio, the moles of silver sulfide are calculated. These moles are multiplied by the molar mass to convert to the grams.
Molar mass of 
= 2(107.87)+32.06 = 247.8 g per mol
The dimensional set up for the complete problem is:
= 
So, the correct choice is B. 4.65 g.
Answer:
B) more genetic variation
B) when the organisms produce offspring
Explanation:
More genetic variation means the species is most likely to not die out whenever the environment changes. Take a group of giraffes with varying neck lengths, for example. If the height of the trees were to change, then less of them would die of starvation.
Genes are created through reproduction. During reproduction, an organism with different genes from its parents occurs, creating more genetic variation. Additionally, mutations can also occur, resulting in genes not from either parent.
The positively charged particle of an atom is called Proton.
The negatively charged particle of an atom is called an electron.
Answer:
Yes.
Explanation:
Substances are made up of matter or matter are made up of tiny molecules or atoms that occur naturally or some are synthetic or man made.
All matter are made up of substances called elements and each elements have its own physical and chemical properties and cannot be broken easily by ordinary chemical reactions.
Of all the 118 elements only 92 occur naturally and 26 are man made or synthetic which are made in the laboratories.
744 atomic mass units (a.m.u)
Explanation:
We know that 1 carbon atoms weighs 12 atomic mass units (a.m.u). Knowing this we devise the following reasoning:
if 1 carbon atom have a mass of 12 atomic mass units (a.m.u)
then 62 carbon atoms have a mass of X atomic mass units (a.m.u)
X = (62 × 12) / 1 = 744 atomic mass units (a.m.u)
