C. Distance from Earth

The observed brightness of a star (the apparent magnitude) to an absolute magnitude, you need to know the distance [d], to the star. Alternatively, if we know the distance and the apparent magnitude [m] of a star, we can calculate its absolute magnitude [d].

Why does it generally take more enthalpy to ignite a solid than a gas or liquid?
Anuta_ua [19.1K]

Answer:

It is due to the nature of the reactants

Explanation:

To ignite a solid, we require more heat component compared to liquids and gases. For ignition to occur, oxygen gas combines with a reactant in most cases.

Some factors affect the rate rate at which a chemical proceeds. One of the factors is the nature of reactants.

The solid phase is very slow while the gaseous phase is rapid and fast.

            solid phase < liquid phase <  gas phase

Gases are free and the molecules move in all direction. They easily combine and react very fast.

Which group on the periodic table is the most reactive
Lostsunrise [7]

Answer:

Group 7 or the Halogens

Explanation:

The halogens occupies the 7th group on the periodic table. The group is made of F, Cl , Br, I and At.

The elements in this group are the most reactive of all elements. They are very reactive because they have just 7 electrons in their outermost shell and they only require an electron to complete their electronic configuration to produce an octet which typically mimics the stable group VIII elements.

This makes them very highly reactive.

How many milliliters are in 425 g of bromine if the density of bromine is 3.12 g/cm3
arlik [135]

Answer:

<h2>136.2 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 425

density = 3.12 g/cm³

We have

volume =  \frac{425}{3.12}  \\  = 136.2 \:  \:  {cm}^{3}

Since cm³ = mL

We have the final answer as

<h3>136.2 mL</h3>

Hope this helps you

All of the cells in the body need oxygen. Hemoglobin molecules in red blood cells transport oxygen through the bloodstream. Oxyg
tankabanditka [31]

Answer:

High partial pressure of oxygen in the tissues.

Explanation:

Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.

When there is lack of oxygen in our bodies, we experience hypoxia.
