The movement of salt molecules in a system and surroundings that have different concentrations follow the osmosis principle. Osmosis is the phenomena where molecules move from lower concentration to higher concentration through a sem-permeable membrane. when the concentration is higher outside, then answer is C. molecules <span>move out of the cell, and the cell will shrink or shrivel.</span>
Answer:
C. 64
Explanation:
Given:
The number of equally likely sample outcomes of a single stage = 4
Unknown:
Total number of elements if there are three stages= ?
Solution;
Probability is the likelihood of an event to occur.
In this problem;
For a single stage, the likely outcome is 4
So therefore;
For the 3 stages 4 x 4 x 4 = 64
Therefore, the total number of elements in the sample space of an experiment with 3 stages is 64

<h3>To find the empirical formula you need the relative atomic mass of each element!</h3>
N = 14
H = 1
S = 32.1
<h3>You can simply change the percentages into full grams</h3>
N = 12.20
H = 6.06
S = 48.45
<h3>Then you use this to find the Number of moles = amount in grams / atomic mass</h3>
N = 12.20 ÷ 14 = 0.8714
H = 6.06 ÷ 1 = 6.06
S = 48.45 ÷ 32.1 = 1.541
<h3>Then divide each number of moles by the smallest value:</h3>
N = 0.8714 ÷ 0.8714 = 1
H = 6.06 ÷ 0.8714 = 6.9 ≈ 7
S = 1.541 ÷ 0.8714 = 1.76 ≈ 2
So that means that there are 1 Nitrogen, 7 hydrogen, and 2 sulfur. This means the empirical formula would be:
NH₇S₂
Hope this helps!
Answer:
B
Explanation:
it depends if the weather was cold but ummm they warm and cold air would mix and turn story and watch out tornadoes could also happen
Answer:
Yes A redox reaction can be a combination reaction.
Two elements are mixed in a combination reaction to produce a single product.
Explanation:
Example: water formula
2H2 + O2 → 2H2O
Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.
2H2 + O2 → 2H2O
