The relative atomic mass of the element is 15.99 and the element is oxygen.

<h3>What is the relative atomic mass of the element?</h3>

Let us note that owing to the fact that elements often have isotopes, the relative atomic mass is not always a whole number. Now we have tp obtain the relative atomic mas from the atomic masses of the elements.

Thus;

X = (15.99 * 0.99762) + (16.999 * 0.00038) + (17.999 * 0.002)

X = 15.95 + 0.0065 + 0.036

X= 15.99

Thus the relative atomic mass of the element is 15.99 and the element is oxygen.

What salt is produced in each of the following neutralization reactions? HNO3(aq)+KOH(aq)→H2O(l)+? HNO3(aq)+Ca(OH)2(aq)→H2O(l)+?
Igoryamba

Answer:

1. KNO3

2. Ca(NO3)2

3. CaCl2

4. KCl

Explanation:

In each of the neutralization reactions, the H from one of the reactant(acid) will combine with the OH from the other reactant (base) to form water while the other elements combine to give the salt as shown below:

1. HNO3 + KOH → H2O + KNO3

The salt produced is KNO3

2. 2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2

The salt produced is Ca(NO3)2

3. 2HCl +Ca(OH)2 → 2H2O + CaCl2

The salt produced is CaCl2

4. HCl +KOH → H2O + KCl

The salt produced is KCl

what is the color of a fabric that absorbs electromagnetic radiation of wavelengths between 400 and 500nm
Umnica [9.8K]

Answer:

Either of the three colors

Violet , indigo , Blue

Explanation:

The different ranges of color produced as per the electromagnetic spectrum are as follows  

• Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm

• Green:   490 - 570 nm

• Yellow:   570 - 585 nm

• Orange:   585 - 620 nm

• Red:   620 - 780 nm

A material absorbing light in the range of 400-500 nm can have three colors –  

•  Violet:   400 - 420 nm

• Indigo:   420 - 440 nm

• Blue:   440 - 490 nm

Why is this considered a theory instead of a hypothesis or a law?
UNO [17]

Answer:

This is considered a hypothesis because it hasn't been confirmed. It is just a guess.

Explanation:

A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. Law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. However, Newton's law doesn't explain what gravity is, or how it works.
