The answer is c. hg (mercury)
Answer:
1
Explanation:
The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.
If no coefficient is shown, we assume it is 1.
NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.
Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
I think its the 3rd one 0.21
Answer is: <span>Double Displacement.
Combustion is reaction with oxygen.
</span>Synthesis is reaction of two or more substances combining to make a more complex
substance.
Decomposition is reaction where one substance is broken down into two or more simpler substances.
Single Displacement is reaction where neutral element metal or nonmetal
become an ion as it replaces another ion in a compound.
<span>Double displacement
reactions (more reactive metals displace metals with lower reactivity).
</span>Neutralization<span>is is </span>reaction<span> in which an </span>acid<span> and a </span>base<span> react quantitatively with each other.</span>
