How do social forces shape technology

1 answer:

Pie2 years ago

Social forces shape technology both in the form of deliberate social activism and also in unconscious ways. For example, in social activism, large demonstrations against oil pipelines can lead to more rapid development of alternatives to fossil fuels. Somewhat unconsciously, the clogging of cars in tight downtown areas in cities and decreasing parking space gave an impetus to develop new forms of rapid transit like subways and electric articulated buses.

The coefficient for sulfuric acid wen reaction between calcium phosphate and phosphoric acid occurs is

three (3)

<h2>explanation</h2>

write a balanced chemical equation for the reaction

that is

Ca3(PO4)2 + 3 H2SO4 →2 H3PO4 + 3CaSO4

since coefficient is number in front of a chemical formula the coefficient of H2SO4 is 3

How many atoms are in 73.9g of potassium oxide

denis-greek [22]

Answer: $4.69(10)^{23} atoms$

Explanation:

Firstly, we have to find the Molecular mass of potassium oxide ( $K_{2}0$ ):

$K$ atomic mass: 39 u

$O$ atomic mass: 16 u

$K_{2}O$ molecular mass: $39(2) g/mol+16g/mol=94 g/mol$

This means that in 1 mole of $K_{2}O$ there are $94 g$ and we need to find how many moles there are in $73.9 g$ $K_{2}O$ :

1 mole of $K_{2}O$ ----- $94 g$ of $K_{2}O$

$X$ ----- $73.9 g$ of $K_{2}O$

$X=\frac{(73.9 g)(1 mole)}{94 g}$

$X=0.78 mole$ This is the quantity of moles in 73.9 g of potassium oxide

Now we can calculate the number of atoms in 73.9 g of potassium oxide by the following relation:

$N_{atoms}=(X)(N_{A})$

Where:

$N_{atoms}$ is the number of atoms in 73.9g of potassium oxide

$N_{A}=6.0221(10)^{23}/mol$ is the Avogadro's number, which is determined by the number of particles (or atoms) in a mole.

Then:

$N_{atoms}=(0.78 mole)(6.0221(10)^{23}/mol)$

$N_{atoms}=4.69(10)^{23} atoms$ This is the quantity of atoms in 73.9g of potassium oxide
