Answer:

Explanation:

The cryosphere—the portion of the Earth's surface where water is in solid form for at least one month of the year—has been shrinking in response to climate warming. ... The important outcome, however, is the change and the response the human social system (infrastructure, food, water, recreation) will have to that change.

The cryosphere the portion of the Earth's surface where water is in solid form for at least one month of the year has been shrinking in response to climate warming.

The cryosphere includes all of the earth's frozen water, including glaciers and sea ice.

The lithosphere is the solid part of the earth made up of rocks, minerals, and other elements except the ocean. It is the  part which present in the outer part of the earth which includes the brittle upper portion of the mantle and crust. The part of  planet where living things can be found from the upper part of the atmosphere to the lower of the oceans and pools that are thermal and made up of the parts of earth where life present in all ecosystem is known as biosphere.

The atmosphere is the thin layer of gases that covers the outer part of the planet. It gives us the many different climates, or broad way of  weather conditions around the world. The hydrosphere includes all of the water on earth from the oceans to glaciers and underground water and it can be liquid, vapour, or ice.

Therefore, the cryosphere the portion of the Earth's surface where water is in solid form for at least one month of the year has been shrinking in response to climate warming.

Answer:

Odessium (Od) has an average atomic mass of 284.45

Explanation:

Average mass is calculated from the isotopes of an element weighted by their relative abundance.

To calculate the relative average mass, you need to find the % of each isotope and use these to calculate the relative average mass

Add all 3 answers to get the relative average mass

Answer:

Decreases  

Explanation:

Answer:

This apparent change in the pitch (or frequency) of sound is called Doppler shift. ... You see these stretched-out light waves as having a lower frequency. Since red is at the low-frequency end of the visible spectrum, we say that light from a receding star is shifted toward red, or red shifted.

Answer: True

Explanation:

Answer:

317.6 mL

Explanation:

Step 1: Write the balanced neutralization equation

MgO + 2 HCl ⇒ MgCl₂ + H₂O

Step 2: Calculate the mass corresponding to 640.0 mg of MgO

The molar mass of MgO is 40.30 g/mol. The moles corresponding to 640.0 mg (0.6400 g) of MgO are:

0.6400 g × (1 mol/40.30 g) = 0.01588 mol

Step 3: Calculate the moles of HCl that react with 0.01588 moles of MgO

The molar ratio of MgO to HCl is 1:2. The moles of HCl are 2/1 × 0.01588 mol = 0.03176 mol

Step 4: Calculate the volume of 0.1000 M HCl that contains 0.03176 moles

0.03176 mol × (1 L/0.1000 mol) = 0.3176 L = 317.6 mL

Beeswax is neither a mineral nor a rock it is supposed to be a heterogenous mixture.

Minerals are defined as a chemical compound which has a well -defined composition and possesses a specific crystal structure.It occurs naturally in the pure form.

If a compound occurs naturally in different crystal structure then each structure is considered as a different mineral.The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.

Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure.It may also have variable composition which is split into separate species.

Physical properties of minerals include color,streak, luster,specific gravity and cleavage.

Explanation:

Answer:

24.32

Explanation:

From the question given above, the following data were obtained:

Isotope A:

Mass of A = 24

Abundance (A%) = 78.70%

Isotope B

Mass of B = 25

Abundance (B%) = 10.13%

Isotope C:

Mass of C = 26

Abundance (C%) = 11.17%

Average atomic mass of Mg =..?

The average atomic mass of Mg can be obtained as illustrated below:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

Average atomic mass = [(24 × 78.70)/100] + [(25 × 10.13)/100] + [(26 × 11.17)/100]

= 18.888 + 2.5325 + 2.9042

= 24.3247 ≈ 24.32

Therefore, the average atomic mass of magnesium (Mg) is 24.32

So, a homogeneous mixture is when the parts that make up the mixture are all mixed in perfectly evenly, so they're only appearing as one uniform substance.

In a heterogeneous mixture, the pieces are not evenly mixed. A pizza has separate parts, like the crust and toppings, so it's a heterogeneous mixture.
