What could you do to change the volume of a gas

Jet001 [13]

Solids and liquids have volumes thatdo not change easily. A gas, on the other hand, has a vol- ume thatchanges to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

What is the land part of the earth called?

Molodets [167]

The Land Hemisphere is the part of the Earth that encompasses the largest portion of land on the planet. Despite being called the Land Hemisphere, the area of water in the hemisphere is greater than that of the area of land present here. The Land Hemisphere has its center at 47°13′N 1°32′W which is located near the French city of Nantes. The Land Hemisphere includes most of Asia and South America and the whole of Africa, Europe, and North America. Seven-eighths of the land area of the Earth is part of this hemisphere

During the following chemical reaction, 46.3 grams of C3H6O react with 73.2 grams of O2

ra1l [238]

Answer:

a) O2 is the limiting reactant

b) 75.70 grams CO2 (theoretical yield)

c) There remains 12.81 grams of C3H6O

d) The actual yield CO2 is 34.29 grams

Explanation:

Step 1: Data given

Mass of C3H6O = 46.3 grams

Mass of O2 = 73.2 grams

Molar mass of C3H6O = 58.08 g/mol

Molar mass of O2 = 32 g/mol

Step 2: The balanced equation

C3H6O + 4O2 → 3 CO2 + 3H2O

Step 3: Calculate moles C3H6O

Moles C3H6O = mass C3H6O / molar mass C3H6O

Moles C3H6O = 46.3 grams / 58.08 g/mol

Moles C3H6O = 0.793 moles

Step 4: Calculate moles O2

Moles O2 = 73.2 grams / 32 g/mol

Moles O2 = 2.29 moles

Step 5: Calculate limiting reactant

For 1 mol C3H6O we need 4 moles of O2 to produce 3 moles CO2 and 3 moles H2O

O2 is the limiting reactant. It will completely be consumed. (2.29 moles).

C3H6O is in excess. There will react 2.29/4 = 0.5725 moles C3H6O

There will remain 0.793 - 0.5725 = 0.2205 moles C3H6O

This is 0.2205 moles * 58.08 g/mol = 12.81 grams

Step 6: Calculate moles of CO2

For 1 mol C3H6O we need 4 moles of O2 to produce 3 moles CO2 and 3 moles H2O

For 2.29 moles O2 we need 3/4 * 2.29 = 1.72 moles CO2

This is 1,72 moles * 44.01 g/mol = 75.70 grams CO2

Step 7: Calculate actual yield

% yield = 45.3 % = 0.453 = (actual yield / theoretical yield)

actual yield = 0.453 * 75.70 = 34.29 grams

How can i make babies

Studentka2010 [4]

Answer with Explanation:

Babies are formed when the sperm cell from the male testicular gonad meets with the women's egg cell (from the ovaries). This penetration causes the "fertilization process." This naturally occurs two weeks from the woman's last day of menstruation. The fertilization allows the egg to rapidly divide. This is followed by "implantation," a process whereby the blastocyte attaches to the woman's endometrium. Around three weeks, the blastocyte is formed into an embryo. This will be called fetus once the woman reaches its 8th week of pregnancy.

This is a brief process regarding your question on how babies are formed.
