Answer: Drugs.com is the site which have all we need regarding medicines and uses of medicines. It give the facility to search A-Z drugs, once you have searched the desired medicine by this feature of site, it further gives information about identification of pills, approval date, and interaction between drug-drug and drug- the food you eating, the manufacturing date of medicines. It doesn't give information about the calculators.
Therefore, (e) is the correct option here.
Answer:
0.726 mol·L⁻¹
Step-by-step explanation:
c = moles/litres
=====
Moles = 29.8 × 1/342.30
Moles = 0.087 06 mol
=====
Litres = 120 × 1/1000
Litres = 0.120 L
=====
c = 0.087 06/0.120
c = 0.725 mol·L⁻¹
Answer:
16.56g.
Explanation:
You need to compare the number of coefficient of the reaction product to find how much water produced. The reaction formula will produce 6 carbon dioxide(CO2) and 6 water (H2O).
If the reaction produces 0.92 moles of carbon dioxide, then the amount of water produced in moles will be: 0.92 moles * (6/6)= 0.92 moles
The molar mass of water is 18g/mol, so the calculation of moles to mass will be: 0.92 moles * (18g/mol)= 16.56g.
Alkali metals are rarely found in pure form because they are so reactive.
Alkali metals are in Group 1 of the Periodic Table.
They need to lose only one valence electron to reach a filled valence shell
Thus, they readily react wirh water and other chemicals in the earth to form compounds.
Idk 18 but here is 20
conductor-a substance that readily conducts
insulator-a substance that does not readily allow the passage of heat or sound
ammeter-an instrument for measuring electric current in amperes.
voltmeter- an instrument for measuring electric potential in volts
current-a flow of electricity which results from the ordered directional movement of electrically charged particles.
potential difference-the difference of electrical potential between two points.
ohmic resistor- resistors that have a constant resistance
non-ohmic resistor- a resistor that's resistance increases as the current increase
power-the capacity or ability to direct or influence the behavior of others or the course of events.
