what is Tyndall effect ?​

Answer:

c

Explanation:

Answer:

1. Greenhouse gas.

2. Carbon sequestration.

3. Greenhouse effect.

Explanation:

Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.

Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.

Matching the descriptions with their term respectively, we have;

1. Greenhouse gas: carbon dioxide, water vapor, methane, nitrogen oxides, and some CFCs that absorb heat and keep it in the earth's atmosphere

2. Carbon sequestration: it's a technology used to capture the carbon released from smokestacks and store it in some part of the environment to keep it out of the atmosphere. Thus, it's a process that is typically used for capturing and the long-term storage of atmospheric carbon dioxide in soil, ocean, plants and geologic formation, so as to reduce global warming or climate change.

3. Greenhouse effect: it's a term used to describe the negative role that greenhouse gases such as methane, water vapor, carbon dioxide etc., play in keeping the earth warm.

Answer: Weather currents change wind tempature and there for change the weather of the seasons.

Answer: C6H6

Explanation:

The molecular formula C₆H₆ represents Benzene. Benzene is colorless, flammable, and has a sweet and gasoline-like odor. It's a toxic chemical, and can cause cancer.

Benzene is a hydrocarbon and used for the manufacturing of products such as plastic, detergents, glues, dyes, and rubber. It can also be used in making wall-filling material.

Answer:

here is the answer. Feel free to ask for more chem help <3

Answer:

The correct option is option C

Explanation:

Loss or gain of electron(s) occurs in a type of attraction known as electrovalent or ionic attraction. In this type, there is transfer (or loss) of electron(s) from a metal atom to become positively charged while a nonmetal accepts (or gains) this electron to become negatively charged.

When this does not happen, two metal atoms can become attached by sharing the same electrons through a form of attraction known as covalent bonding. Here, the two atoms share electrons (known as shared pair) together to achieve there octet configuration on the outermost shell.  

Answer:

10

Explanation:

how many electron-containing d orbitals are there in an atom of tin? name the element in the 4th period whose atoms have the same number of highest-energy-level elctrons as tin

10, germanium

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the total number of orbitals containing electrons in an atom of tin are 10 orbitals.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The electronic configuration of tin is 1s² 2s² 2p⁶ 3s²3p⁶ 4s² 3d¹⁰ 4p⁶ 5s²4d¹⁰ 5p² or [Kr] 5s² 4d¹⁰ 5p². The total number of orbitals containing electrons in an atom of tin are 10 orbitals. tin an element that belongs to p block of periodic table.

Therefore, the total number of orbitals containing electrons in an atom of tin are 10 orbitals.

Answer:

Risky behavior or risk-taking behavior is defined according to Trimpop (1994) as “any consciously, or non-consciously controlled behavior with a perceived uncertainty about its outcome, and/or about its possible benefits, or costs for the physical, economic or psycho-social well-being of oneself or others.” In addition to this broad definition, there are other definitions of risky behavior depending on the field of research. While in the economic view, risk is defined in terms of the variability of possible monetary outcomes, in the clinical literature, the risk is generally defined as exposure to possible loss or harm (Schonberg, Fox, & Poldrack, 2011). Turner et al. (2004) described risk-taking behavior further as either a socially unacceptable volitional behavior with a potentially negative outcome in which precautions are not taken, such as speeding, drinking and driving, drugs abuse, unprotected sex and so on.

Answer:

13924g/mol is the molar mass of the protein

Explanation:

What is the molar mass of the protein.

The osmotic pressure of a solution, π, is defined as:

π = c*R*T

Where π is osmotic pressure = 2.054torr* (1atm/760torr) = 2.70x10⁻³atm

c is molar concentration of the protein,

R is gas constant = 0.082atmL/molK

And T is absolute temperature = 298K

Solving the molar concentration:

c = π / RT

c = 2.70x10⁻³atm / 0.082atmL/molK*298K

c = 1.106x10⁻⁴ moles protein / L

The moles of protein in 150mL = 0.150L:

0150L * (1.106x10⁻⁴ moles protein / L) = 1.659x10⁻⁵ moles protein

The molar mass is the ratio of mass and moles:

0.231g / 1.659x10⁻⁵ moles protein =

Answer: The equilibrium will shift in the direction of [tex]NH_3[/tex]

Explanation:

The chemical equation for the aqueous solution of ammonia follows:

[tex]NH_3+H_2O\rightleftharpoons NH_4^++OH^-[/tex]

According to Le-chtelier's principle:

If there is any change in the variables of the reaction, then the equilibrium will shift in that direction of equilibrium to minimize the effect.

If we add more amount of [tex]NH_4^+[/tex] to the solution, more of the products will be present. But according to Le-chtelier's principle, to minimize this effect, the equilibrium will shift in the backward direction that in the direction of [tex]NH_3[/tex]

Hence, the equilibrium will shift in the direction of [tex]NH_3[/tex]

B. 2.14 x 10^-19 J

Explanation:

The energy of a wave of light can be obtained using the equation:

E = h*c/λ

Where E is the energy in joules,

λ is wavelength = 930nm = 930x10⁻⁹m

h = Planck's constant = 6.626x10⁻³⁴Js

c = Speed of light = 3.00x10⁸m/s

Replacing:

E = 6.626x10⁻³⁴Js*3.00x10⁸m/s/930x10⁻⁹m

E = 2.14x10⁻¹⁹J

Answer:

Only β+ decay

Explanation:

In positron emission, a proton is converted into a neutron and a positron. An anti neutrino is a particle that serves the purpose of balancing the spins.

During positron emission, the mass number to the daughter nucleus is the same as that of the parent nucleus but the atomic number of the daughter nucleus is less than that of the parent nucleus by one unit.

Positron emission increases the neutron/proton ratio.

Answer:

ΔS⁰ = -181.1J/molK

Explanation:

ΔS⁰ of a reaction is defined as the sum of the entropies of the reactants times its reaction coefficient minus the sum of the entropies of the products times its reaction coefficient. For the reaction in the problem:

ΔS⁰ = 2*S{NaCl(s)} - (2*S{Na(s)}+S{Cl2(g)})

ΔS⁰ = 2*72.1J/molK - (2*51.1J/molK + 223.1J/molK)
