A neutralization reaction is a _________ replacement reaction that starts with an ________ and a __________ and ends with ______

Alexeev081 [22]

Answer:

Double, acid, base, water, salt.

Explanation:

The general reaction of a neutralization is:

X(OH) + YH → H₂O + XY

If you see, the reaction is a double replacement reaction because the cation and the anion of the two reactants switch places, forming two new compounds or products.

Always, the reaction starts with an acid and a base and will produce water and a salt.

I hope it helps!

Calculate the density of an object with a mass of 3.8 g, that when placed in a 10.0 mL graduated cylinder with an initial volume

Arturiano [62]

Answer : The density of an object is 0.93 g/mL

Explanation : Given,

Mass of an object = 3.8 g

Initial volume = 4.5 mL

Final volume = 8.6 mL

First we have to calculate the volume of an object.

Volume of an object = Final volume - Initial volume

Volume of an object = 8.6 mL - 4.5 mL

Volume of an object = 4.1 mL

Now we have to calculate the density of an object.

Formula used:

$\text{Density}=\frac{\text{Mass of an object}}{\text{Volume of an object}}$

Now putting all the given values in this formula, we get:

$\text{Density}=\frac{3.8g}{4.1mL}$

$\text{Density}=0.93g/mL$

Therefore, the density of an object is 0.93 g/mL

10. A "neutral atom" is one that has the same number of _______ and ______

Paladinen [302]

Answer:

Protons and Electrons

Explanation:

Protons are positively charged particles in an atom and electrons are negatively charged. These charges cancel out to make a neutral atom. For example, Carbon has 6 protons (+6) and 6 electrons (-6). 6 - 6 is 0, making it neutral.

What is the mathematical equation used when solving calorimetry problems? What does each variable in the equation represent?

liubo4ka [24]

Answer : The mathematical equation used when solving calorimetry problems is:

$q=m\times c\times \Delta T}$

Explanation :

Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.

Formula used :

$q=m\times c\times \Delta T}$

where,

c = specific heat capacity of calorimeter

m = mass of a substance

q = heat required

$\Delta T$ = change in temperature of substance
