Answer:

Indonesia Bank one of the largest consumers of electricity or energy in any form depends on fossil fuels for energy.

Explanation:

Utilisation of solar energy for their day to day basis such that the energy need is met would mean less use of fossil fuels and lesser greenhouse gases.

And also damage to the environment and this is a very important step by Indonesia to do their bit towards environment by controlling pollution and being largest consumer turning green would mean a lot.

Most modern medications are given in doses of milligrams. Thyroid medications, however, are typically given in doses of microgra

leonid [27]

Answer:

0.125 mg

Explanation:

The correct answer would be 0.125 mg

According to the conversion factor, one milligram of a sample is equivalent to one thousand micrograms of the same sample.

milligram = $10^{-3}$

microgram = $10^{-6}$

Hence,

1 milligram = 1000 micrograms or 1 microgram = $10^{-3}$ milligram

Therefore, 125 micrograms will be:

125/1000 = 0.125 milligram

Lead has a density of 11.4 g/cm^3. What is the density in kilograms per cubic meter?

Vikentia [17]

The density in kg/m³ = 1.14 x 10⁴

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³ or m³

A density of Lead : ρ = 11.4 g/cm³

the density in kg/m³ :

$\tt 11.4~\dfrac{g}{cm^3}\times \dfrac{kg}{10^3~g}\times \dfrac{cm^3}{10^{-6}~m^3}=\boxed{\bold{1.14\times 10^4~\dfrac{kg}{m^3}}}$

BRAINLIESTTT ASAP! PLEASE HELP ME :)

Iteru [2.4K]

Answer:

The mass of the products left in the test tube will be less than that of the original reactants.

Explanation

The equation for the reaction is

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

1.0 3.0 3.9 0.1

Assume you started with 1.0 g of Mg.

It will react with 3.0 g of HCl to form 3.9 g of MgCl2 and 0.1 g of H2

Mass of reactants = mass of products

1.0 g + 3.0 g = 3.9 g + 0.1 g

4.0 g = 4.0 g

The Law of Conservation of Mass is obeyed.

However, your test tube and its contents will weigh 0.1 g less than it did before the reaction.

Does that contradict the Law of Conservation of Mass? It does not.

One of the products was the gas, hydrogen, and it escaped from the test tube. You weren't measuring all the products, so test tube and its contents weighed less than before.
