Answer:
Na(OH)4
Explanation:
Look at the charges and add them up
Na(OH) Na(OH)
Answer:
B. Green solution density is 1.06 g/ml and blue solution density is 1.20 g/ml
Explanation:
Density is given as,
D = Mass / Volume
Red Solution,
D = 25 g / 25 mL
D = 1 g/mL
Green Solution,
D = 26.5 g / 25 mL
D = 1.06 g/mL
Yellow Solution,
D = 28.2 g / 25 mL
D = 1.128 g/mL
Blue Solution,
D = 30 g / 25 mL
D = 1.20 g/mL
endothermic means it absorbs energy while exothermic means it releases energy. remember this.
hola, esta pregunta es bastante difícil pero está bien, no lo sé, lo siento :) :)
