The volume of 0.175 M Na3PO4 solution that is necessary to completely react withn 95.4 ml of 0.102 M cuCl2 is
<u>calculation</u>
<u> </u><em> Step 1: </em> write the equation for reaction
3CuCl2 (aq) + 2Na3Po4 → Cu3(PO4)2 + 6 NaCl
Step 2 : find the moles of CuCl2
moles = molarity x volume in liters
volume in liters = 95.4 /1000 =0.0954 L
moles is therefore = 0.0954 L x 0.102 M= 0.00973 moles
Step : use the mole ratio to calculate the moles of Na3Po4
The mole ratio of CuCl2 : Na3PO4 is 3:2 therefore = 0.00973 x2/3= 0.00649 moles
Step 4 : find the volume of Na3PO4
volume = moles/molarity
= 0.00649 mole / 0.175=0.037 M
Answer:
A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. What is the specific heat capacity of iron?
Explanation:
Answer:
This question has no options but it can be answered based on the understanding of the function of ribosomes.
The effect is the deficiency of proteins in the cell.
Explanation:
Ribosomes are one of the most important cellular organelles found in living organisms. Infact, they are so important that they are found in both the prokaryotic and eukaryotic cell. Ribosome functions in PROTEIN SYNTHESIS as they are the site where the mRNA encoding protein building blocks (amino acids) undergo their translational process.
According to this question, an analyzed cell is found to be missing most of its ribosomes. This means that the function performed by the missing organelle, which is SYNTHESIS OF PROTEINS, will be lacking. Hence, that particular cell will be PROTEIN-DEFICIENT.

No, this item is not made of pure silver because if it has been made from pure silver that it would have displaced only 1.16cm³ of water but due to the addition of some other low-density element it displaces 1.9cm³ of water.
<u>For pure silver</u>
density of pure silver is = 10.49 g/cm³
mass of silver = 12.2 gram
since, density = mass/volume
volume = mass/density
= 12.2/10.49 cm³
= 1.16 cm³
But the actual displaced water is <u>1.9cm³</u>, which means some other element of lower density has been added.
Therefore, it is clear that the given jewelry is not made of pure silver.
