The number of sulfate ions : 2.2 x 10²³
<h3>Further explanation</h3>
Reaction
Al₂(SO₄)₃⇒2Al³⁺+3SO₄²⁻
mol Al₂(SO₄)₃(MW=342,15 g/mol) :
mol of sulfate ions (SO₄²⁻)
1 mol = 6.02 x 10²³ particles (ions, molecules, atoms), so for 0.366 mol :
Answer is 456 mmHg.
<em>Explanation;</em>
This is a simple unit conversion problem.
1 atm = 760 mmHg
Hence,
0.600 atm = (760 mmHg
/ 1 atm) x 0.600 atm
= 456 mmHg
Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.
The relationships among those units as follows
1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
Answer:
89.7 billion in scientific notation = 8.97 × 1010.

Answer:
SUBSTANCES
Explanation:
According to this question, Jasmine is conducting an experiment in order to see how much temperature change occurs when three different substances are heated. Based on this experiment, the INDEPENDENT VARIABLE, which is the variable that is changed or manipulated is SUBSTANCES.
A controlled experiment is an experiment where all other variables except the INDEPENDENT VARIABLE is kept the same or unchanged. The independent variable is the only variable allowed to change, which in this case is the SUBSTANCES USED.
Answer:
Gravity
because the earth which pulls any object towards it center and the velocity is achieved
