Answer:
The corect answer would be C.
Explanation:
The flow rate set at a differentt time would be the correct measurement beecause wats and speed add up to your main answer.

Explanation:
Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
Answer:
0.718L of 0.81M HCl are required
Explanation:
Based on the reaction:
Cd(s)+2HCI(aq) → H2(g)+CdCl2(aq)
<em>1 mol of Cd reacts with 2 moles of HCl</em>
<em />
To solve this question we must, as first, find the moles of Cd. With the moles of Cd we can find the moles of HCl needed to react completely with the Cd. With the moles and the molarity we can find the volume:
<em>Moles Cd -Molar mass: 112.411g/mol-:</em>
32.71g * (1mol / 112.411g) = 0.2910 moles Cd
<em>Moles HCl:</em>
0.2910 moles Cd * (2 moles HCl / 1mol Cd) =
0.5820 moles HCl
<em>Volume:</em>
0.5820 moles HCl * (1L / 0.81moles) =
<h3>0.718L of 0.81M HCl are required</h3>
<h2>Answer:</h2>
The correct answer is option C which is cell can be a plant cell or an animal cell.
Explanation:
- The statement is is that cell has cell membrane. Cell membrane is the outer covering membrane which is present in both cells. While cell wall is a external hard membrane present only in plant cells.
- In the statement D, the presence in the large molecule usually in the center of cell is the indication of plant cell. It gives the upright direction in plants and it stores large amount of water and food.
- Hence the correct answer is option C.
