Answer: Weight

Explanation:

Matter is anything that has mass and occupies space.

Weight of an object is the force acting on an object by virtue of its mass. It has units of dynes , Newton etc.

weight= $mass\times acceleration$

m= Given mass

g= acceleration due to gravity

Mass is the amount of matter contained in a substance. It can be measured in units of kilograms (kg), grams (g), milli grams (mg) etc.

Thus weight is dependent on strength of gravity field.

Im pretty sure it weight because when we are on different plants with a different amount of gravitational pull our weight changes

hope this helps :)

How many moles of CaCO3 are needed to react with 12.5 mol SO2

grandymaker [24]

<h3><u>Answer;</u></h3>

= 12.5 Moles of CaSO3

<h3><u>Explanation</u>;</h3>

The reaction between CaCO3 and SO2 is given by the equation.

CaCO3(s) + SO2(g) → CaSO3(aq) + CO2(g)

The mole ratio between CaCO3 and SO2 is 1 : 1;

1 mole of CaCO3 reacts with 1 mole SO2 to form CaSO3 and CO2

Therefore;

<em>12.5 moles of SO2 will require 12.5 moles of CaSO3</em>

Can anyone help with 5 through 8? Please :(

Aleksandr [31]

Answer:

The answer to your question is below

Explanation:

5) Fe₂O₃(s) + 3H₂O ⇒ 2Fe(OH)₃ (ac) Synthesis reaction

6) 2C₄H₁₀(g) + 13O₂(g) ⇒ 8CO₂ (g) + 10H₂O Combustion reaction

7) 2NO₂ (g) ⇒ 2O₂ (g) + N₂ (g) Decomposition reaction

8) H₃P (g) + 2O₂ (g) ⇒ PO (g) + 3H₂O Single replacement reaction

Select the lewis structure for xeo2f2 which correctly minimizes formal charges.

IrinaVladis [17]

Answer:

explanation and image attached

Explanation:

Our aim is to draw a structure of XeO2F2 whith the least formal charges. We must remember that the compound has 34 valence electrons.

To obtain the least formal charges then Xe must have a total of twelve electrons on its valence shell instead of eight.

The other atoms around the central Xe atom are arranged as shown in the image attached.
