Answer:

electrical energy

Explanation:

A heating element converts electrical energy into heat through the process of resistive (otherwise known as Joule heating). The electric current passing through the element encounters resistance, which produces heat.

Sort these six events from the earliest to the most recent. 1. Democritus proposes the existence of atoms 3rd 2. Dalton's atomic

Nitella [24]

Explanation:

1. Democritus proposes the existence of atoms

2. Dalton's atomic theory

3. J. J. Thomson discovers the electron

4. Rutherford's gold foil experiment

5. Bohr model

6. Schrödinger's Wave Mechanics model of the atom

The first idea about matter containing atoms dates back to Greek philosophers. One of them was Democritus .

In 1808 Dalton put forward his atomic theory

In 1897 J.J Thomson discovered cathode rays using his gas discharge tube experiment.

In 1911, Ernest Rutherford proposed the nuclear model of the atom using experiments on the gold foil.

Neils Bohr in 1913 suggested his own atomic model

Erwin Schrodinger formulated the wave equation of electrons

Sodium carbonate (NaCO3) is sometimes used as a water-softening agent. Suppose that a worker prepares a 0.730 M solution of NaCO

elena55 [62]

Answer : The mass of solute in solution is $1.09\times 10^2g$ .

Solution : Given,

Molarity = 0.730 M

Volume of solution = 1.421 L

Molar mass of sodium carbonate = 105.98 g/mole

Formula used for Molarity :

$Molarity=\frac{w}{M\times V}$

where,

w = mass of solute

M = Molar mass of solute

V = volume of solution in liter

Sodium carbonate is solute and water is solvent.

Now put the given values in above formula, we get the mass of solute in solution.

$0.730mole/L=\frac{w}{(105.98g/mole)\times (1.412L)}$

By rearranging the terms, we get

$m=109.247g=1.09\times 10^2g$

Therefore, the mass of solute in solution is $1.09\times 10^2g$ .

Which is a positive effect of the technology advance of going from a compass to a gps

egoroff_w [7]

Answer:

Compass - Gps

Explanation:

I belive the pro's and cons are

GPS you are trusting a little man made device

the direction you to give you directions

are going on and that it won't break or die

a device not a paper map

Compass

You can see north east south and it is usually carefully crafted for o outdoors but it has no roads and

west on the compass and if given no directions, extremely

you can see the roads follow directions confusing until you learn it

like go south then east.
