Select the correct structure that
corresponds to the name.
2-hexyne
A. CH3CH2CH2C=CCH3
B. CH3C = CCH2CH2CH3
C. both
Answer:
c) both
Explanation:
hey, could you check the question once because I suppose it's 2-hexyne when there's a triple bond and 2-hexene when there's a double bond between Carbon atoms. As of the question asked, it's c) both but it's 2-hexene due to presence of double bond between Carbon atoms.
do tell me as well. have a good day :-))
Answer:
(C) Both
Explanation:
Due to my calculations, I have come up with conclusion that this is indeed the correct answer for the problem.

What volume in Liters is needed to make a .99M solution with 5.3 moles of CuCl2?
Answer:
[tex]\boxed {\boxed {\sf 5.35 \ L}}[/tex]
Explanation:
Molarity is a measure of concentration in moles per liter.
[tex]molarity= \frac{moles \ of \ solute}{liters \ of \ solution}}[/tex]
We know the molarity of the solution is 0.99 M and there are 5.3 moles of the solute, CuCl₂.
1 molar (M) is equal to 1 mole per liter. 0.99 M is equal to 0.99 moles of CuCl₂ per liter.So,
molarity= 0.99 mol CuCl₂/L moles of solute = 5.3 mol CuCl₂liters of solution = x (unknown)Substitute these values into the formula.
[tex]0.99 \ mol \ CuCl_2 / L =\frac{5.3 \ mol \ CuCl_2}{x}[/tex]
Now, solve for x by isolating the variable. First, cross multiply.
[tex]\frac {0.99 \ mol \ CuCl_2}{1}=\frac {5.3 \ mol \ CuCl_2}{x}[/tex]
[tex]0.99 \ mol \ CuCl_2 /L *x= 5.3 \ mol \ CuCl_2*1[/tex]
[tex]0.99 \ mol \ CuCl_2 /L *x= 5.3 \ mol \ CuCl_2[/tex]
x is being multiplied by 0.99 mol CuCl₂/L. The inverse of multiplication is division. Divide both sides of the equation by 0.99 mol CuCl₂/L .
[tex]\frac {0.99 \ mol\ CuCl_2 / L*x}{ 0.99 \ mol\ CuCl_2 \ L }=\frac {5.3 \ mol \ CuCl_2}{0.99 \ mol\ CuCl_2 \ L }[/tex]
[tex]x=\frac {5.3 \ mol \ CuCl_2}{0.99 \ mol\ CuCl_2 \ L }[/tex]
[tex]x=5.35353535354 \ L[/tex]
Let's round to the hundredth place. The 3 in the thousandth place tells us to leave the 5 in the hundredth place.
[tex]x \approx 5.35 \ L[/tex]
Approximately 5.35 liters are needed to make a 0.99 M solution with 5.3 moles of solute.

An 18.7 g sample of platinum metal increases in temperature from 21.2C to 23.5C
when 5.7 J of heat are added. What is the specific heat of platinum?
Answer:
132.53 J/kg.°C
Explanation:
Applying,
Q = cm(t₂-t₁)................ Equation 1
Where Q = amount of heat, c = specific heat capacity of platinum metal, m = mass of platinum metal, t₁ = initial temperature, t₂ = Final temperature.
Make c the subeject of the equation
c = Q/m(t₂-t₁).............. Equation 2
From the question,
Given: Q = 5.7 J. m = 18.7 g = 0.0187 kg, t₁ = 21.2°C, t₂ = 23.5°C
Substitute these values into equation 2
c = 5.7/[0.0187×(23.5-21.2)]
c = 5.7/0.04301
c = 132.53 J/kg.°C
3. If a gas has a pressure of 32.1 psi at a temperature of 25°C, then what is the new pressure if the temperature is increased to 75°C?
Answer:
P2 = 37.5 psi
Explanation:
P1 = 32.1 psi
T1 = 25°C + 273 = 298K
T2 = 75°C + 273 = 348K
P2 = ?
P1/T1 = P2/T2
or
P2 = (T2/T1)P1
= (348K/298K)(32.1 psi)
= 37.5 psi

Determine the pH of the solution with a [H+]=5.00 x 10^-12.
Answer:
pH = 11.3
Explanation:
Given that,
The concentration of [H⁺] is [tex]5\times 10^{-12}[/tex]
We need to find the pH of the solution. We know that,
[tex]pH=-log[H^+][/tex]
Put all the values,
[tex]pH=-log[5\times 10^{-12}]\\\\pH=11.3[/tex]
So, the pH of the solution is equal to 11.3.
How many atoms are in 4 CH4? Does the subscript have any effect on the answer?
Answer:
If there's 4 molecules of CH4, then there will be 4 atoms of carbon and 16 atoms of hydrogen. (However, if it's just 1 molecule of CH4, then 1 carbon atom and 4 hydrogen)
Explanation:
Yes, the subscript does have an effect on the answer. The subscript indicates how much of a type of atom there is in a molecule. For example, 1 singular molecule of CH4 contains 1 carbon atom and 4 hydrogen atoms. Due to the subscript (4), it tells us that there are 4 hydrogen atoms. In this case, 4 molecules of CH4 contains 4 carbon atoms and 16 hydrogen atoms.

I have four neutrons and I'm metallic. Who am
I?
According to the electronic configuration, beryllium has four neutrons and is metallic in nature.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

- How much power does it take to lift a
1,000 N load 10 m in 20 s?
Answer:
"500 Joule/sec" is the right answer.
Explanation:
The given values are:
Force,
F = 1000 N
Velocity,
s = 10 m
Time,
t = 20 s
Now,
The power will be:
= [tex]\frac{Force\times Velocity}{Time}[/tex]
On putting the values, we get
= [tex]\frac{1000\times 10}{20}[/tex]

how many electrons does an element have if its atomic number is 20
Answer:
20 electrons
A neutral atom with atomic number 20 will have 20 electrons.
The atomic number is, by definiton, the number of protons in an atom's nucleus but for a neutral atom it's also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.

Water circulates through Earth's water cycle by changing state state its acidity its acidity its turbidity
Complete question is;
Water circulates through Earth's water cycle by changing its _____.
A. state
B. acidity
C. turbidity
D. composition
Answer:
A: State
Explanation:
We can talk about this by observations about the states of water in the Earth's water cycle and even nature.
For example, water changing from liquid to steam(gas) in evaporation; under certain temperatures/conditions snow undergoes sublimation directly from solid to gas and also undergoes melting from solid to liquid; water vapour in the atmosphere undergoes condensation and cooling to form rain.
Thus, we can say that water circulates through the Earth's water by changing it's state.
