Answer:
-3,89
Explanation:
First to consider is that the reaction is raising the temperature of the solution, so it's an exothermic reaction.
The enthalpy can be calculated by the following equation:
First we need to calculate the mass using the density and the volume:
⇒
Then we have Cp = 3,74 Joules/gram°K ΔT = -3,33 °C (cause of exothermic reaction)
Replacing in the formula:
It's not. It's equivalent to the transfer of that many elementary charges <u>every second</u> .
The elementary charge (charge on an electron) is
1.60 x 10⁻¹⁹ coulomb / electron.
The number of electrons in a Coulomb is the reciprocal of that number.
6.25 x 10⁻¹⁸ electrons / Coulomb.
There's the number. 1 Coulomb <em>per second</em> is called 1 Ampere.
Answer:
Autonomy
Explanation:
Dialectics theory represents a relationship that define one communication between individuals. This theory is mainly focused on the struggle that occurs in a relationship.
In dialectics theory, autonomy is a term used to indicate one desire to be with another person but remain apart. autonomy is referred to as the control of one's life without being with them.
The Answer: 55 N
Reason: Because they are pushing in the same direction, their force of N gets added.
1. 30 + 25 = 55
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
