Answer:
condensation
Explanation:
Frost forms when an outside surface cools past the dew point. The dew point is the point where the air gets so cold, the water vapor in the atmosphere turns into liquid. This liquid freezes. If it gets cold enough, little bits of ice, or frost, form

Calculate the energy required to heat 622 g
mercury from 37°C to 42°C. The specific
heat capacity of Hg(l) is 0.138 J/g.° C.
Answer in units of cal.
Answer:
102.58 cal.
Explanation:
Given data:
Mass of mercury = 622 g
Initial temperature = 37°C
Final temperature = 42°C
Specific heat capacity of mercury = 0.138 J/g.°C
Energy required = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 42°C - 37°C
ΔT = 5°C
Q = 622 g × 0.138 J/g.°C × 5°C
Q = 429.18 J
J to cal:
429.18 J × 1 cal /4.184 j
102.58 cal.

The half-life of carbon-14 is 5,730 years. Dating organic material by looking for C-14 can't be accurately done after 50,000 years. Suppose a fossilized tree branch originally contained 4.30 grams of C-14. How much C-14 would be left after 50,000 years?
Answer:
0.010g of C-14 would be later after 50,000 years
Explanation:
The kinetics of radioactive decay follows the equation:
Ln (N / N₀) = -kt
Where N could be taken as mass after time t,
N₀ initial mass = 4.30g;
k is rate constant = ln 2 / t(1/2)
= ln 2 / 5730years = 1.2097x10⁻⁴ years ⁻¹
Replacing:
Ln (N / 4.30g) = -1.2097x10⁻⁴ years ⁻¹ * 50000 years
N / 4.30 = 2.36x10⁻³
N =
0.010g of C-14 would be later after 50,000 yearssodium hydroxide reacts with excess hydrochloric acid. calculate the mass of sodium hydroxide required to produce 117g of sodium chloride
NaoH+HcI→ NaCl +H2O
Na0H=23+16+l= 40 9m
Nacl=23 +35.5 =58.5 gm
mass of NaOH required=117x40/ 58.5 =80 gm
Molar mass of NaOH = 23+16+1 =40g/mol
Molar mass of NaCl = 23+35.5 =58.5g/mol
To produce 58.5g NaCl 40g NaOH is required
So, to produce 117g NaCl {(40/58.5)×117}g = 80g NaOH is required.

Which of the following is a definition for an interstitial alloy?
a
an alloy in which the atomic sizes of the components are different
b
an alloy in which the atoms of the components in an alloy are about the same size
c
an alloy in which some of the atoms of the components are about the same size and some are different
d
a metal in which all of the atoms are of the same element
Answer:
c
Explanation:
An interstitial compound or interstitial alloy is a compound that is formed when an atom of sufficiently small radius sits in an interstitial “hole” in a metal lattice. Examples of small atoms are hydrogen, boron, carbon and nitrogen. These compounds are important industrially, for example some transition metal carbides and nitrides.

Explanation:
Determine la concentración de 10 ml de HCl que fueron valorados con 5 ml de NaOH 0.01 M. Seleccione una: a. 0.04 M b. 10 M c. 1 M d. 0.01 M e. 0.005 M
Answer:
0,005 M
Explanation:
Dado que:
Concentración de ácido (CA) = lo desconocido
Volumen de ácido (VB) = 10ml
concentración de base (CB) = 0.01 M
Volumen de base (VB) = 5 ml
Número de moles de ácido (NA) = 1
Número de moles de base (NB) = 1
Desde;
CAVA / CBVB = NA / NB
CAVANB = CBVBNA
CA = CBVBNA / VANB
CA = 0.01 × 5 × 1/10 × 1
CA = 0,005 M

What are some of the ways that people can Reduce their use of fossil fuels?
Answer:
By using renewable energy sources.
Explanation:
You need to satisfy a quota of energy for (whatever country you live in). People do this by using the cheapest way of producing the most energy, the most efficient. Sounds great right? Wrong! It stuffs our atmosphere with harmful gasses like carbon dioxide. You can reduce the use of these fossil fuels by using renewable energy sources such as windmills, watermills, and most notable, solar panels!
Solar panels. Generating electricity with solar power instead of fossil fuels can dramatically reduce greenhouse gas emissions, particularly carbon dioxide (CO2). ... By going solar, you can reduce demand for fossil fuels, limit greenhouse gas emissions, and shrink your carbon footprint.

Which mass and atomic number is correct for the following isotope: carbon-14
explain your answer
Answer:
Explanation:
Isotope notation is of the form
A
Z
X
where
Z
is the atomic number (number of protons),
A
is the mass number (sum of protons and neutrons), and X is the element.
In Carbon- 14 , 14 is the mass number (sum of protons and neutrons). This is our A .
Carbon has the atomic symbol C , and it has 6 protons. This is the atomic number, or A . Thus, the isotope notation for Carbon- 14 is 14 6 C

what is the name of sc(oh)3
Answer:
Scandium(III) hydroxide
Explanation:
May I have brainliest please? :)
The name of the chemical compound Sc(OH)₃ is "scandium hydroxide."
A polyatomic ion is a charged chemical species composed of two or more atoms that are covalently bonded together and carry an overall electric charge. Unlike simple ions, which are single atoms with a positive or negative charge, polyatomic ions are groups of atoms with a net positive or negative charge due to the gain or loss of electrons.
In this compound:
"Sc" represents the chemical symbol for scandium, which is the metal cation in the compound.
"(OH)₃" represents three hydroxide ions (OH⁻) bound to the scandium cation.
The hydroxide ion (OH⁻) is a polyatomic ion that consists of one oxygen atom and one hydrogen atom, and it carries a negative charge.
So, the name of the compound Sc(OH)₃ is scandium hydroxide.
