Conductivity, malleability, and high melting points. Hope this helps :)
1- thé everyday use of kinematic basically the speed for something it’s the magnitude.
2-the speed of something in a certain direction
2a- They are both related by speed.
3-the capacity of a vehicle which gains speed in a short time
4-it’s an attraction of all matter (not sure on this one)
Answer:
= 67.79 g
Explanation:
The equation for the reaction is;
4Cr(s)+3O2(g)→2Cr2O3(s)
The mass of O2 is 21.4 g, therefore, we find the number of moles of O2;
moles O2 = 21.4 g / 32 g/mol
=0.669 moles
Using mole ratio, we get the moles of Cr2O3;
moles Cr2O3 = 0.669 x 2/3
=0.446 moles
but molar mass of Cr2O3 is 151.99 g/mol
Hence,
The mass Cr2O3 = 0.446 mol x 151.99 g/mol
<u> = 67.79 g
</u>
The correct answer is H2SO3 I took the assignment already
