Velocity is the change in position divided by the time . In your problem, it should be expressed in meters per second. To solve, you must divide the distance, 4.56 meters, by the time it takes to travel that distance, which is 3.42 seconds -----> 4.56/3.42 = 1.333 meters per second is the velocity of the mouse
B. Aluminum, Al3+, aluminum ion is correct
Chloride would be negative, Iron has Fe for the symbol, potassium is K....
Answer:
A process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Explanation:
Pretty much just not a physical reaction or otherwise
0.3268 moles of PC15 can be produced from 58.0 g of Cl₂ (and excess
P4)
<h3>How to calculate moles?</h3>
The balanced chemical equation is
The mass of clorine is m(
) = 58.0 g
The amount of clorine is n() = m()/M() = 58/70.906 = 0.817 mol
The stoichiometric reaction,shows that
10 moles of yield 4 moles of 
;
0.817 of yield x moles of
n() = 4*0.817/10 = 0.3268 mol

The following reaction: H2 + I2 → 2HI, is an example of synthesis reaction
<u>Explanation:</u>
<u>Synthesis reaction:</u>
- In simple words, synthesis reaction can be stated as two or more material merge to form a new material.
- A synthesis reaction is always exothermic since they deliver power in the form of heat and light.
- When the metal and nonmetals are combined they produce an ionic compound.
- A synthesis reaction is essentially the reversal of decomposition reaction.
- The example of Synthesis reaction would be
- 2 H2(g) + O2(g) -->2 H2O(g)
- 3 H2(g) + N2(g)--> 2 NH3(g)
