Reduced air pressure also has a serious effect on the human body. Reduced air pressure means that there is less oxygen available to the body. For lungs to inflate, the air pressure in your lungs has to be less than the air outside the lungs. This is because air moves from high-pressure areas to low-pressure areas.

As blood travels through the body, oxygen is used up, and the blood becomes oxygen poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

Explanation:

The spectator ions would be the ions that don't comprise the precipitate in this reaction. You have four ionic species here: Pb²⁺, NO₃⁻, H⁺, and SO₄²⁻. Since Pb²⁺ and SO₄²⁻ combine, as you are told, to form the precipitate, that leaves H⁺ and NO₃⁻ (or, in normal text, H+ and NO3-) to be the spectator ions.

Edit: NO3- might be interpreted ambiguously since it's not immediately clear that the NO3 is a polyatomic ion with a -1 charge and not an NO compound with a 3- charge, so it should be written as [NO3]- or (NO3)-.

The net ionic reaction shows the reaction without the spectator ions. In this case, that would be: Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s).

With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

Answer:

Arrhenius Base

Explanation:

"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

Answer:

The answer would be 15, letter D.

Explanation:

Since it has 5 electrons in its outermost shell, it will be located in group 15 in the periodic table.

The electron configuration of an atom of an element for the electrons in the s and p orbitals 15th group number of the element in the periodic table option D is correct.

Tha common electronic configuration of 15th group elements in ns2 np3, Group 15 elements in the modern periodic table are known as the pnictogens which means suffocation in Greek language.

This group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb) and bismuth (Bi).

The group 15 elements consist of five valence electrons. Due to this the elements can either lose five electrons or gain three electrons in order to attain the stable configuration. The general electronic configuration of nitrogen family is ns 2 np 3.

therefore , because of ns2 np3 option D is correct.

Answer:

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.

The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

Answer:

359.3g of Na₂CO₃ are required

Explanation:

When sodium carbonate, Na₂CO₃ reacts with HCl, NaCl and H₂O are produced as follows:

Na₂CO₃ + 2HCl → 2NaCl + CO₂ + H₂O

Where 1 mole of sodium carbonate produce 2 moles of NaCl

To solve this question, we must find the moles of sodium carbonate required to produce the 6.78 moles of NaCl. With this mass and the molar mass we can find the mass of sodium carbonate as follows:

Moles Na₂CO₃:

6.78 moles NaCl * (1mol Na₂CO₃ / 2mol NaCl) = 3.39 moles Na₂CO₃

Mass Na₂CO₃ -Molar mass: 105.99g/mol:

3.39 moles Na₂CO₃ * (105.99g / mol) =

Answer:

2.00 M KOH

Explanation:

Divide moles by volume and make sure your volume is in LITERS, not mL.

0.0400 mol KOH / 0.0200 L = 2.00 M KOH

A sample of 0.0400 mol potassium hydroxide, KOH was dissolved in water to yield 20.0 ml of solution. The molarity of the solution is 2.00 M KOH.

Molarity is the measure of the concentration of any solute in per unit volume of the solution.

[tex]M = \dfrac{n}{V}[/tex]

Given, the 0.0400 mol potassium hydroxide

20.0 ml volume

Putting the values in the equation

[tex]\dfrac{0.0400 mol }{ 0.0200 ml} = 2 M[/tex]

Thus, the molarity of the solution is 2.00 M KOH.

bromine has 1, hydrogen has 4 and nitrogen has 1 therefore equaling 6

The number of atoms in NH₄Br is six.

An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is surrounded by one or more negatively charged electrons. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.

Atoms are the basic building blocks of matter. Anything that takes up space and anything with mass is made up of atoms.

In the given formula, there is one N atom, four H atoms and one Br atom making a total of six atoms.

Therefore, the number of atoms in NH₄Br is six.
