Answer:

Na k

Explanation:

because na is a metal and potassium is also a metal and both are active metal so is less likely to react as no bond is formed between them

The difference between speed and velocity is that speed is the time rate at which an object is moving along a path. While velocity is the rate and direction of the object’s movement.

if something is travelling at a constant velocity are the forces balanced or unbalanced?
Unbalanced

if something changes motion, are forces balanced or unbalanced?
Unbalanced. If the forces on the object is equal and in opposite directions, then the forces are balanced, then there would be no change in motion


what are the three ways to accelerate?
1. A change in velocity
2. A change in direction
3. A change in both velocity and direction

3. Students measured the mass of the reactants and products for a combustion reaction they observed.
coldgirl [10]

Answer:

A. Students made a measurement error, because ending with more products is impossible.

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction. If there is excess mass in the product, the students have made an error of some kind.

What is the chemical formula for zinc phosphate?
solong [7]
First, we have to find the chemical formula for zinc ion and phosphate ion.

Zinc ion is a cation, and its formula is Zn^2+,
This is because zinc atom requires 2 outer shell electrons to be removed in order to become stable.

On the other hand, phosphate ion is a anion, and its formula is PO4^3-.

In order to find the chemical formula of this ionic bond, we need to make sure their charges are balanced.

To do this, take 2+ and 3-, their least common multiple is 6, so in order to turn both charges into 6+ and 6-, we need to determine how many of that ion is needed.

So to make 2+ to 6+, we need 3 zinc ions ( +2 x 3 = 6).
And to make 3- to 6-, we need 2 phosphate ions (-3 x 2 = - 6).

Now we can just combine the chemical formulas with the number of that ion needed (you can ignore the charge)
Therefore, your answer should be Zn3(PO4)2.
