frozen [14]4 years ago
8 0

Answer:

Some of the various things that humans do to the environment is pump CO2 into the air with Fossil Fuels and using Power Plants, Cutting down trees make more CO2 which can make the Earth hotter and cause Global Warming. Some natural things that can tend to affect climate can be changes in Volcanic activity, Solar activity with the sun, and Earth's orbit around the sun.

Explanation:

It may seem crazy how Earth's orbit around the sun make climate change, but how else would 4 seasons exist. The orbit tends to be in an oval shape. The top parts of the oval, would represent winter and fall because of the distance between the sun decreases. The closer sides of the oval however, would represent Summer and spring because those are the warmer months and show that Earth is closer to the sun.

15.63 moles of HgO are needed to produce 250. 0 grams of Oxygen.

<h3>How we calculate moles from masses?</h3>

Moles of any substance can be calculated as:

n =W/M, where

W = given mass

M = molar mass

Given chemical reaction is:

2HgO → 2Hg + O₂

From the stoichiometry of the reaction, it is clear that:

2 mole of HgO = produce 1 mole of O₂

Given mass of O₂ = 250 grams

Molar mass of O₂ = 32 g/mole

Mole of produced O₂ = 250g / 32g/mole = 7.81 moles

Now, 7.81 moles of O₂ = produced by 2×7.81 = 15.63 moles of HgO

Hence, option (3) is correct i.e. 15.63 moles is the required moles.

The density of a liquid can be determined by weighing a known volume of the liquid in a graduated cylinder. the data from the ex
Kipish [7]

Answer:- density of the liquid is 0.21 gram per mL.

Solution:- density=\frac{mass}{volume}

From given data, mass of cylinder = 10.4 g

mass of cylinder along with liquid = 11.7 g

So, mass of liquid = 11.7 g - 10.4 g = 1.3 g

Volume of liquid = 6.2 mL

Let's divide the mass by the volume to get the density of the liquid:

density=\frac{1.3g}{6.2mL}

density = 0.21\frac{g}{mL}

So, the density of the liquid is 0.21 gram per mL.

What does an-ite or-ate ending in a polvatomic ion mean?
satela [25.4K]

Answer:

An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.

ate = one more O than -ite

Explanation:

Example:

NO2 is nitrite

NO3 is nitrate

You can see that the molecules are made of the same elements, however they have more or less of one of the elements (i.e. oxygen).
