Platinum is one of the most dense elements (d = 21.5 g/cm3). What is the volume of a 10.0 g sample of the metal?
kvasek [131]

Answer:

0.465

Explanation:

To find the volume of a substance, divide the mass by the density.

M/D = V

10.0 / 21.5 = 0.4651163

Then round to 3 significant figures: and the density is 0.465

**PLEASE SHOW YOUR WORK**Calculate how much energy would be necessary to convert 250.0 grams of ice at -30°C to steam at 145°C.
garri49 [273]

Answer:

Q= mc∆T(ice) + mLF(ice) + mc∆T(water) + mLV(water) + mc∆T(steam)

m=250 g = 0.25 kg = ¼ kg c(ice)= 2100 J/kg.K c(water)= 4200 J/kg.K LF(ice)= 333.7 kJ/kg LV(water)= 2256 kJ/kg c(steam)= 2080 J/kg.K

Explanation:

Q= ¼ × 2100 × (0°-(-30°)) + ¼ × 333700 + ¼ × 4200 × (100°-0°) + ¼ × 2256000 + ¼ × 2080 × (145°-100°)

Q= 15750 + 83425 + 105000 + 564000 + 23400

Q= 791575 J

What types of mixtures are these? (Homogeneous Mixture Hetergeneous Mixture)
salantis [7]

Explanation: A <u>homogeneous mixture</u> is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout.

A<u> heterogeneous mixture</u> has components whose proportions vary throughout the sample. The components of a heterogeneous mixture are visible and not uniform throughout. A heterogeneous mixture is simply any mixture that is not uniform in composition.

a) Peanuts and almonds mixed  together in a bowl  : The components(Peanuts and almonds) are visible in a bowl and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

b) Bucket full of sand and gravel  : The components(sand and gravel) are visible in a bucket and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

c) Cup of tea and sugar  : The components(tea and sugar) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

d) Food coloring dissolved in water : The components(Food coloring and water) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.
