Answer:
1st one is the answer water cannot be purified by nature pls add me in brainliest
The correct answer here would be A because its chemical name is sodium carbonate which is more basic than sodium bicarbonate, if you added soda ash to the solution then that would increase the ph of the solution
Answer:
16.68 m/s
Explanation:
The following data were obtained from the question:
Height (h) = 14.2 m
Initial Velocity (u) = 0 m/s
Final velocity (v) =?
Thus, the velocity (v) with which the ball hit the ground can be obtained as follow:
v² = u² + 2gh
NOTE: the acceleration due to gravity (g) = 9.8 m/s²
v² = u² + 2gh
v² = 0² + 2 × 9.8 × 14.2
v² = 0 + 278.32
v² = 278.32
Take the square root of both side
v = √278.32
v = 16.68 m/s
Therefore, the velocity with which the ball hit the ground is 16.68 m/s
<h3>
Answer:</h3>
The products of the reaction are; AgCl and NaNO₃
<h3>
Explanation:</h3>
In this question we need to know what is a double displacement reaction;
- A double displacement is a type of replacement reaction in which salts or ionic compounds exchange cations and anions to form new compounds as the products.
- In this case, the complete double replacement reaction is;
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
- The reaction is also a precipitation reaction as it forms a precipitate as one of the products that is silver chloride (AgCl).
- Therefore, the products of the reaction are; AgCl and NaNO₃
