ima give brainless even tho i donno what it is but help pls Equau!! Remember to convert degrees Celsius (°C) to Kelvin (K) by adding 273. 4. A gas at temperature 273 K and volume 2.5 L is warmed to 300 Kat constant pressure . What is the new volume of the gas? 1 5. A gas at temperature 20°C is warmed to 100 °C at constant pressure. The initial volume is 3.0 L.. What is the new volume of the gas? 6. A gas of volume 2.4 L is cooled from 20 °C to -20° C at constant pressure. What is the new volume of the gas? 01 v1=p2v​

Why is carbon ideal for making different compounds?

Balance and in which category does it fit in? single or double displacement or synthesis or decomposition? (a) k2 o → k + o2 (b) na + i2 → nai (c) cu(no3 )2 + naoh → cu(oh)2 + nano3 (d) kclo3 → kcl + o2 (e) ca(no3 )2 + hbr → cabr2 + hno3 (f) sn(oh)2 → sno + h2 o (g) p4 + n2 o → p4 o6 + n2 (h) fe + al2 (so4 )3 → feso4 + al (i) alcl3 + na2 co3 → al2 (co3 )3 + nacl (j) c3 h6 + o2 → co2 + h2 o

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
