Answer:

running helps my heart beat

Answer 2

Answer:

Exercise: The easiest and most effective way to achieve a lasting lower heart rate is to do regular exercise. 2. Stay hydrated: When the body is dehydrated, the heart has to work harder to stabilize blood flow. Throughout the day, drink plenty of sugar- and caffeine-free beverages, such as water and herbal tea.

A hydrate of CoCl2 has a mass of 15.80 g before heating. After heating the mass of the anhydrous compound is found to be 9.32 g explain how you would determine the formula of the hydrate and then write out the full name of the hydrate

Answers

Explanation:

Molar mass of Cobalt (II) chloride = 129.8g/mol

Moles of CoCl2 = 9.32/129.8 = 0.0718mol

Mass of H2O lost after heating = 15.80 - 9.32 = 6.48g

Moles of H2O = 6.48/18 = 0.36mol

Mole ratio of CoCl2 : H20

= 0.0718mol : 0.36mol

= 1 : 5

Hence the formula is CoCl2 . 5H2O, which is Copper (II) chloride pentahydrate.

For your 13th answer in #4, what is the other name for this particle?

Answers

Answer:

The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.

Explanation: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

Answer:

Explanation:

The really interesting characteristic of the atmosphere is that each layer has a different temperature range. That is truly incredible when you list them.

The first layer is the troposphere. It is the layer closest to the earth's surface. It is 12 km high and goes from 15oC to - 56oC

The next layer is the Stratosphere. It is 38 km above the  Troposphere and the temperature goes from -56 to -2.5

The third layer is Mesosphere. It is 40 km above the Stratosphere and the temperature goes from -2.5 to -86.5

The next layer is the Thermosphere.  It is 710 km above the Mesosphere. It goes from - 86.5 to 1200o C So this goes from - 100 roughly to + 1200. That is a massive distance. It speaks wonders of how balanced this planet really is.

The final layer is the Exosphere. It goes up to 3000 km. The temperature is consistently at 1200oC

What I don't understand is how you get the layers from a 13 answer of something. What is the first name of the particle? That would seem to have nothing to do with this answer. Please explain because this was a good deal of work that might be for nothing. Mind you the answer is very interesting.

Someone help with this ions and isotopes worksheet?

Answers

Isotopes are atoms of the same element that have different numbers of neutrons. Protons are positively-charged particles found in the nucleus of an atom.

Electrons are negatively-charged particles found in the outer shell of an atom. The charge on an element is determined by the number of protons and electrons present in the atom.

a.) Li+:  number of protons = 3

Number of electrons = 2

charge of Li+ = +1

b.) Be2+: number of protons = 4

Number of electrons = 2

charge of Be2+ = 2+

c.) C4+: number of protons = 8

Number of electrons = 4

charge of C4+ = 4+

d.) O2-: number of protons = 8

Number of electrons = 10

charge of O2- = -2

e.) N3-: number of protons = 7

Number of electrons = 10

charge of N3- = -3

f.) C4- : number of protons = 4

Number of electrons = 4

charge of C4- = -4

g.) 14C6: The mass number = 14

Atomic number = 6

Number of neutrons = 8

h.) 18O8:  The mass number = 18

Atomic number = 8

Number of neutrons = 10

i.) 19F9:  The mass number = 19

Atomic number = 9

Number of neutrons = 10

j.) 40Ca20:  The mass number =40

Atomic number = 20

Number of neutrons = 20

k.) 37Cl17:  The mass number = 37

Atomic number = 17

Number of neutrons = 20

l.) 238U92:  The mass number = 238

Atomic number = 92

Number of neutrons = 146

What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.12 g/mol

Answers

Answer:

C4H8O4

Explanation:

Let (CH20)x

C=1*12.01=12.01     (12.01, 1.01, 16.00 Avg mass of elements)

H=2*1.01=2.01

O=1*16.00=16.00

12.01 + 2.01 + 16.00 = 30.03

120.12/30,03=4

==> (CH2O)4 = C4H8O4

The molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex] is equal to [tex]C_4H_8O_4[/tex].

Given the following data:

Empirical formula = [tex]CH_2O[/tex]Molar mass = 120.12 g/mol.

Scientific data:

Molar mass of oxygen = 16 g/mol.Molar mass of hydrogen = 1 g/mol.Molar mass of carbon = 12 g/mol.

To determine the molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex]:

First of all, we would find the molar mass of [tex]CH_2O[/tex]:

[tex]CH_2O =12 +(1\times2)+16\\\\CH_2O =30\;g/mol[/tex]

For molecular formula:

[tex](CH_2O)n = 120.12\\\\30n = 120.12\\\\n=\frac{120.12}{30}[/tex]

n = 4.0

[tex](CH_2O)_4 = C_4H_8O_4[/tex]

Answers

The height of the object : 600 mm

Further explanation

Given

d object=360 mm(object distance)

d image=90 mm(image distance)

Required

h object

Solution

focal length = f :

[tex]\tt \dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}\\\\\dfrac{1}{f}=\dfrac{1}{360}+\dfrac{1}{90}\rightarrow f=72~mm[/tex]

The magnification :

[tex]\tt M=\dfrac{d_i}{d_o}=\dfrac{90}{360}=0.25[/tex]

[tex]\tt M=\dfrac{h_i}{h_o}\\\\0.25=\dfrac{150}{h_o}\rightarrow h_o=600~mm[/tex]
