Answer:

1016 kg

Explanation:

Hello,

In this case, the required conversion is carried out by knowing that 1 lb is equivalent to 0.453592 kg, in such a way:

2240lb*\frac{0.453592kg}{1lb} =1016kg

Best regards.

Answer: 963.2 kg

Explanation: Mass is defined as the amount of matter contained in the substance. It has units of g, kg, cg, pounds etc.These units are inter convertible.

1lb = 0.43 kg

Given: mass = 2240 lb

Thus if 1 lb is equal to 0.43 kg

2240 lb is equal to =\frac{0.43}{1}\times 2240=963.2kg

Thus mass of the object is 963.2 kg.

Answer:

320 g.

Explanation:

Hello!

In this case, according to the balanced chemical reaction, we can compute the grams of copper I chloride produced by each reactant, as shown below:

m_{CuCl}^{by\ Cu}=3.23molCu*\frac{2molCuCl}{2molCu}*\frac{99.0gCuCl}{1molCuCl}  =320gCuCl\\\\m_{CuCl}^{by\ Cl_2}=1.64molCl_2*\frac{2molCuCl}{1molCl_2}*\frac{99.0gCuCl}{1molCuCl}  =325gCuCl

Thus, since copper produces the fewest grams of CuCl, we infer it is the limiting reactant, therefore the correct mass of copper I chloride is 320 g.

Best regards!

Answer 2.04

Explanation

Electronegativity decreases down the group and increases across the period in the periodic table.

In the period two of the periodic table,we have the following values for electronegativities with respect to its elements.

Li...........0.98

Be.........1.57

B..........2.04

C.........2.55

N..........3.04

O...........3.44

F...........3.98

Ne........n.a
