Answer:
Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial. Collections of tissues joined in units to serve a common function compose organs.
Explanation:
I'm assuming that you want to covert atmospheres into mmHg.
mmHg is exactly like torr: there are 760 of them in an atmosphere.
The conversion would be 760 mmHg = 1 atm
Knowing this, simply multiply 2.48 * 10^3 by 760:
2.48 * 10^3 * 760 = 1,884,800 mmHg.
But wait! I'm assuming you probably meant to write 2.48 * 10^-3, since 1,884,800 is an awfully big number.
In that case:
2.48 * 10^-3 * 760 = 1.8848 mmHg

A precipitation reaction is a reaction that yields an insoluble product.
When two solutions which could react are mixed together, they interact with each other and products are formed. These products could be aqueous solutions or solids.
When a mixture of two aqueous solutions react chemically to yield an insoluble product, we can say that a precipitation reaction has taken place.
We shall now proceed to fill in the missing products in each of the reactions;
a) Ca(NO3)2 (aq) + CuSO4 (aq) → CaSO4(s) + Cu(NO3)2 (aq)
b) 2KC2H302 (aq) + COSO4 (aq) → Co(C2H302)2 (s) + K2SO4(aq)
c) 2K3PO4 (aq) + 3Mg12 (aq) → 6KI(aq) + Mg3(PO4)2 (s)
d) FeCl3 (aq) + 3NH4OH (aq) → Fe(OH)3 (s) + 3NH4Cl(aq)

Answer: 186 g/mol
Explanation:
Weight of solvent (water)=100 g = 0.1 kg (1 kg=1000 g)
Molar mass of solute (impurity) = ?
Mass of solute (impurity) added = mass of solution - mass of solvent (water) = (118- 100) = 18 g
= change in freezing point
= freezing point constant for water = 
The molecular mass of the impurity is 186 g/mol.
Answer:
24 hours and 50 minutes
Explanation:
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
