A student has a 5. 00 gram sample of calcium chloride (cacl2) solid. How many moles of calcium chloride are contained in this sample?
Answer:
0.0451 moles ≅ 0.04 moles
Explanation:
We are able to calculate how many moles of calcium chloride (CaCl₂) are in 5.00 g sample, by dividing the mass into the molar mass (MM) of the compound:moles = mass/MMFirst, we calculate MM of CaCl₂ from the chemical formula, using the molar mass of the elements Ca and Cl:MM CaCl₂ = (1 x MMCa) + (2 x MMCl) = 40 g/mol + ( 2 x 35.453 g/mol) = 110.9 g/mol.
Finally, we calculate the moles from the mass and MM:moles of CaCl₂ = mass/(MM CaCl₂) = 5.00 g/(110.9 g/mol) = 0.0451 moles ≅ 0.04 moles
So your answer comes out as 0.0451 moles ≅ 0.04 moles.

What must be the value of x so that the two triangles are congruent by sss postulate
Answer:
17x-8=11x+4
Add 8 to both sides:
17x=11x+12
Subtract 11 x from both sides:
6x=12
Divide both sides by 6:

An engineer finds that a large wind turbine for generating energy rotates at a constant angular speed of 2. 0 rad/sec. Through what angle does it rotate in one minute?
The constant angular speed of the wind turbine is 19.1 rpm
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Conversion from rad/s to rpm is:
1 rad/s = 60/2π rpm
Hence:
2 rad/s = 2 * 60/2π rpm = 19.1 rpm
The constant angular speed of the wind turbine is 19.1 rpm

Which small-scale mutation would be most likely to have the least negative effect on the function of a protein?
Answer:
A substitution of one base for another within the sequence. A base deletion near the start of a gene. A base deletion near the end of the coding sequence, but not in the terminator codon.
Explanation:
Hopefully this helps :)
Answer:
The small-scale mutation that would most likely have the least negative effect on the function of a protein is ; ( A ) A substitution of one base for another within the sequence.
A substitution of one base for another within the sequence of a protein will cause an insignificant/silent mutation within the protein sequence and this mutation will not be evident in the protein.
When a base is deleted either near the start of a gene or near the end of the coding sequence, it will have a significant effect because this will change the sequence of the DNA ( due to the deletion of at least one nucleotide ).
Hence we can conclude that the small-scale mutation that would most likely have the least negative effect on the function of a protein is ; A substitution of one base for another within the sequence.

Arc cd is of the circumference of a circle. What is the radian measure of the central angle? radians radians radians radians
If the arc cd is K times circumference, then the central angle is K times 2pi.
(where K is any real between 0 and 1).
How to find the central angle?
The question is incomplete, but it can be answered in a general form.
We know that for a circle of radius R, the circumference is:
C = 2*pi*R
While for an arc of central angle θ, the length of the arc is:
A = θ*R
Now, if we know that the arc is K times the circumference (Where K can be any real number between 0 and 1), then we have that:
A = θ*R = K*2*pi*R
Now we can solve that for the central angle:
θ = K*2*pi*R/R = K*2*pi
θ = K*2*pi
So, if the arc cd is K times circumference, then the central angle is K times 2pi.
