1) State the balanced chemical equation
Na3 PO4 + 3 AgNO3 → 3NaNO3 + Ag3 PO4
sodium phosphate silver nitrate sodium nitrate silver phosphate
2) State the molar ratios
1 mol Na3PO4 : 3 mol AgNO3 : 3 mol NaNO3 : 1 mol Ag3 PO4
3) As you see 3 moles of Silver Nitrate react with 1 mol of Na3 PO4, then you will need.
The you need to use the molar ratio 1:3 to calculate the number of moles of sodium phosphate
1 mol Ag NO3 * [ 1 mol Na3 PO4 / 3 mol Ag NO3] = 0.33 mol Na3 PO4
Answer: 0.33 mol sodium phosphate
Volcanic eruptions are caused by earth's internal heat sources.
All the other choices are atmospheric or external earth.
Answer:
It does not always retain the properties of the substances that make it up
It requires heat energy to make
Explanation:
A compound is a chemical substance composed of two or more kinds of atoms or elements joined together in a definite grouping.
The properties of compounds are distinct from those of individual elements that are combined in its make up.
- To produce a compound, a chemical change must take place
- As with most chemical changes, heat is required to drive the change.
- So, to form compounds, some amount of heat is needed to cause the change.
It changes rocks and minerals by water, ice, acids, salt, and changes in the temperature. Once the rock has been broken down a process named erosion happens, it transports bits of rocks and minerals away
Answer: here is a description of what they look like since I cannot see the diagram.
Mitochondria- wavy line
Ribosomes- little dots
Chromosome- X
Nucleus- Circle with bite taken out of it
Endoplasm- Bubble
Nuclear membrane- Outer layer/bubble
Golgi-wavy circle thing
Vacuole- Bigger circle (but not nucleus)
Cytoplasm- its the jelly on the inside
Cell wall- only in plant cells, looks like a box
Cell membrane- The outmost part of the animal cell, the barrier.
I sure hope this helps!!!
