Answer:

In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is called precipitation. Often the precipitate emerges as a suspension. Precipitates can form when two soluble salts react in solution to form one or more insoluble products.

Pieces of dry ice become smaller through the process of condensation. true or false.

stiv31 [10]

Totally false. There is no process of condensation for dry ice as it either sublimes from dry ice to co2 or sublime back to dry ice

3. All the following steps need to be followed when naming alkanes, except A. locating the longest carbon chain. B. using prefix

gulaghasi [49]

Answer:

D. beginning numbering at the end farther from the first branch.

Explanation:

In naming alkanes, the longest continuous chain in the compound is first considered and this gives the name of the compound intended. The name of the substituent on the compound are also arranged in alphabetical order when naming the compound.

The carbon atoms are numbered in the parent chain or ring to indicate where branching or substitution takes place. The direction of numbering is chosen such that the lowest numbers possible is given to the branches or substituents. If we begin the numbering at the end farther from the first branch, we won't give the lowest numbers possible to the branches.

How to solve a balanced equation

geniusboy [140]

Explanation:

To balance a chemical equation, there are so many approaches to solve the problem.

A balanced chemical equation is one that obeys the law of conservation of matter.

According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".

This implies implies that equal number of atoms must be on both sides of the equation.

There are two main approaches to balancing chemical equation;

Inspection
mathematical equation

We can inspect the equation and affix the proper coefficients to combining species.

Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:

For example:

H₂ + O₂ → H₂O

mathematically;

aH₂ + bO₂ → cH₂O

conserving:

H : 2a = 2c

O: 2b = c

let a = 1

c = 1

b = $\frac{1}{2}$

multiply by 2 to give;

a = 2, b = 1 , c= 2

2H₂ + O₂ → 2H₂O

Why does decreasing the volume of gas cause the pressure to increase if temperature is constant

Yuri [45]

There's less space, causing the air particles to collide with the walls of the container more frequently. Pressure is that energy caused by molecules striking a surface. Thus, compacting air molecules leads to higher pressure.
