Help!!<br> Classify each diagram as an element a compound or mixture

Black_prince [1.1K]

Answer:

1. Mixture

2. Compound

3. Compound

4. Element

Explanation:

Number 1 shows two completely different types of compounds in the same space, so it is a mixture.

Numbers 2 and 3 are compounds because there aren't different types compounds as in Number 1, but the same compound repeated. 2 is a compound because while all of the circles are the same element, they are connected. O2 for example, oxygen, is a compound.

Number 4, finally, is all of the same substance, non-connected, so it shows an element.

A plant fertilizer contains 19 % nitrogen (N) by mass. In a container of soluble plant food, there are 10.0 oz of fertilizer. Ho

Evgesh-ka [11]

Answer:

53.87g

Explanation:

Given parameters:

Percentage by mass of Nitrogen in fertilizer = 19%

Mass of fertilizer = 10.0oz

Unkown:

Mass in grams of Nitrogen in the container = ?

Solution

To solve this problem, we first find the percentage of mass of nitrogen in the fertilizer by a taking a percentage of the given mass of the fertlilizer:

Mass of Nitrogen in ounces of the fertilizer =

$\frac{19}{100}$ x 10 = 1.9oz

Since we are expected to express this in grams:

1oz = 28.35g

1.9oz = 1.9 x 28.35, 53.87g
