Answer:
The answer to your question is:
Explanation:
3.- Convert each into
1.56 x 10⁴ = 15600
0.00259 x 10⁵ = 259
0.00259 x 10³ = 2.59
0.56 x 10⁻² = 0.0056
0.000459 x 10⁻¹ = 0.0000459
0.0209 x 10⁻³ = 0.0000209
3.69 x 10⁻² = 0.0369
13.69 x 10⁻² = 0.1369
736.9 x 10⁵ = 73690000
6.9 x 10⁴ = 69000
4.- Calculate the following
a) 2653000 = 2.653 x 10⁶
b) -2687 = - 2.687 x 10³
c) 2.532 x 10²⁴
d) 1470 = 1.47 x 10³
Explanation:
A chemical property is defined as the property that brings changes in chemical composition of a substance.
For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.
On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.
For example, shape, size, mass, density etc are all physical properties.
Thus, we can conclude that these may all be classified as chemical properties of a substance.
Answer:
Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O → CO + H2.
Increase, because you need heat to melt a solid to a liquid, so the temperature will have to get greater.
