It would send its neutron to another atom. Therefore, the neutron < the proton, so it would change to a positive ion.

Answer:

A. 0.17 moles

Explanation:

Every 10 grams Glucose to mol = 0.05551 mol

30 moles= 0.166503, round up to .17

**The density of a rectangle : ρ = 0.372 g/cm³**

<h3>Further explanation</h3>

**Given**

The volume of rectangle : 395 cm³

Mass : 147 g

**Required**

The density

**Solution**

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

Density formula:

ρ = density

m = mass

v = volume

Input the value :

ρ = 147 g : 395 cm³

**ρ = 0.372 g/cm³**

**Answer:**

(4) concentrated and supersaturated

**Explanation:**

At 50.°C, 90g of KNO3 lies above the solubility curve [on the Regents Reference Table G]. This indicates that the solution is supersaturated, meaning it contains more solute than will naturally dissolve, and was formed when a saturated solution cooled. Furthermore, the percent concentration of this solution is 90% KNO3 making this solution concentrated. This can be calculated using the formula for mass percent concentration.

Percent Mass = <u>Mass of Solute (g)</u> x 100

Mass of Solution (g)
