Answer:

The answer to your question is:

1.- CO

2.- 0.414 moles of CO2

Explanation:

Data

2CO + O2 ⇒ 2CO2

CO = 0.414 moles

O2 = 0.418

Process

theoretical ratio CO/O2 = 2/1 = 1

experimental ratio CO/O2 = 0.414/0.418 = 0.99

Then the limiting reactant is CO

2.-

2 moles of CO --------------- 2 moles of CO2

0.414 moles of CO --------- x

x = (0.414 x 2) / 2

x = 0.414 moles of CO2

Calculate the number of moles in 1.8gram of h2o

Rzqust [24]

Answer:

~.1058 Moles

Explanation:

The formula for this question is the following.

1 mole of a compound/molar mass of the compound.

First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.

1 mole of H2O/ 17.01 g/mol H2O

We now know that in 1 mole of H20 there is 17.01 g.

Take 1.8g and divide it by 17.01, you get your answer.

Carbohydrates like sugars and starches are made of only three elements: carbon (C), hydrogen (H), and oxygen (O). How is it poss

lara31 [8.8K]

Answer:

See explanation

Explanation:

A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.

Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.

This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.

How many moles of SnF₂ will be produced along with 48 grams of H₂? *

KIM [24]

Answer: 24 moles of $SnF_2$ are produced.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

${\text{Moles of} H_2}=\frac{48g}{2g/mol}=24moles$

$Sn+2HF\rightarrow SnF_2+H_2$

According to stoichiometry :

1 mole of $H_2$ is accompanied with = 1 mole of $SnF_2$

Thus 24 moles of $H_2$ is accompanied with = $\frac{1}{1}\times 24=24moles$ of $SnF_2$

Thus 24 moles of $SnF_2$ are produced.

Two objects are described below.

mojhsa [17]

Answer:

Both objects are moving.

Explanation:

Object 1 is moving because the unbalanced force acting on the skateboard is causing it to either move slower or move faster. An example of this is when the skateboard is going down the hill. The unbalanced force is caused by the gravity which speeds up the skateboard.

Object 2 is also moving although it has a balance force; however, it is moving at a "constant speed." This is because the force of thrusting forward is being counteracted by a friction force of the same magnitude. Forces that are equal in magnitude and of opposing directions causing the speed to be constant. So, the bicycle is still moving.
